The door mechanism of the Alfa Romeo Spider 105/115 provides secure closing of the doors, smooth operation of the windows and handles and a clean fit of the doors of the open roadster. As a manufacturer, supplier and spare parts specialist for classic Alfa Romeo parts, we carry the parts of the door mechanism for the entire production period of the Spider from 1966 to 1993. As lock, closing mechanism, window regulator and door handles differ in form and fixing depending on the series and the year, the correct assignment to the series and the year is decisive. Ordering by the model name alone easily leads to unsuitable parts and avoidable returns, whereas the precise stating of series, year and side allows a reliable selection. The following overview shows how the product groups of the door mechanism relate to the series and years and what to watch for in the selection. The door mechanism on the Spider is model-dependent and year-dependent and should therefore be selected precisely by the series, the year and the side. As a reliable door mechanism is equally important for operation, comfort and safety, a matching and complete selection has a particular importance. Especially on the open roadster the doors should close securely, sit cleanly and be easy to operate.
Model and series reference
On the Spider the door mechanism depends on the series and the year. Lock, striker, lock mechanism, window regulator and inner as well as outer door handles each follow the series, as form, hole pattern and fixing can differ over the years. Anyone who knows the series and the year of their Spider can compile lock, striker, lock mechanism, window regulator, inner and outer door handles, lock cylinders as well as the associated small parts and guides precisely and without wrong orders. The series, the year and the side left or right are decisive in the selection of the door mechanism. Anyone who knows these points on their vehicle exactly can assign the matching parts reliably and extend the door mechanism step by step. As lock, striker, handle, window regulator and mechanism are matched to one another in function and fixing, coherent parts should be regarded and selected together, so that the door mechanism works cleanly and smoothly in the end and the doors close securely.
Shared across the range or model dependent
The door mechanism of the Spider follows the open body with two doors and differs in form and fitting from that of the coupé and the four-door saloon. It would be wrong to assume that lock, window regulator and door handles are freely interchangeable between Spider, GT Bertone and Giulia, since form, fitting and arrangement depend on the body and the year. Within the Spider series lock, closing mechanism and door handles can differ over the years, while individual small parts and seals can be similar. Common over several years are individual fixings and small parts, but the visible and load-bearing parts of the door mechanism follow the series, the year and the side. Anyone wishing to use parts from another stock or a donor vehicle should therefore check carefully whether they suit the series, the year and the side of the Spider, since lock, closing mechanism, window regulator and door handles in particular were changed several times over the years. So a fixing is often the same, but lock, handle and mechanism follow the respective series, the year and the side left or right.
Part types and product groups
The range of the door mechanism is divided into several groups. These include the door lock and the striker, the lock mechanism with its levers and rods, the window regulator with its guides, the inner and the outer door handle as well as all associated small parts. Added to this are the lock cylinders, the locking and the associated fixings, which are important for secure closing and smooth operation of the doors. There are also seals, guides and small fixing parts, which are easily overlooked during a repair but are important for a reliable door mechanism and ensure a smooth run. These groups cover the entire door mechanism from the lock and striker via the lock mechanism and the window regulator through to the inner and outer door handles and can be selected by series, year and side, so that a step-by-step repair remains easy to plan and individual parts can be exchanged one after another. A complete and matching door mechanism ensures secure closing, smooth operation as well as a clean, tight fit of the doors.
Differences by year, series or version
The most important difference lies in lock, closing mechanism and door handles, which can differ in form, hole pattern and fixing depending on the series and the year. The window regulator and the associated guides also follow the respective series and the year and should be chosen to match. Anyone ordering parts should therefore state series, year and the side left or right precisely so that lock, handle, window regulator and mechanism match. Even with apparently similar parts a close look is worthwhile, because small differences in form, hole pattern, lever length and fixing decide whether a part fits without adaptation and the door mechanism works cleanly and securely in the end. Anyone renewing the door mechanism should therefore choose the parts matching the series, the year and the side rather than mixing parts of different years, as otherwise lock, handle and mechanism do not work cleanly together.
Notes on selection
For a reliable selection it is advisable to determine the series and the year of the Spider before ordering, to define the side left or right and to narrow down precisely which part of the door mechanism is needed. A photo of the existing part and its fixing helps with assigning the correct series and year and avoids queries when ordering. The matching small parts, guides and fixings should be ordered at the same time when changing a part, as they ensure a secure and smooth run. With mixed stock from several sources a comparison with the series-correct version is worthwhile so that form, hole pattern, fixing and function match exactly and later rework is avoided. Anyone fully renewing the door mechanism should plan lock, closing mechanism, window regulator, inner and outer door handles and the associated small parts together from the start and select them to match the series and the year. As a manufacturer and spare parts specialist we advise on the correct assignment and supply both original parts and high-quality reproductions in good quality, so that even older vehicles can be fully restored.
Frequently asked questions
Is the door mechanism the same across all years?
No. Lock, closing mechanism, window regulator and door handles can differ depending on the series and the year.
Do Spider door mechanism parts also fit GT Bertone or Giulia?
No. Form, fitting and arrangement depend on the respective body, the door mechanism is model-dependent and year-dependent and not freely interchangeable.
Are lock and handle available individually?
Yes. Lock, striker, window regulator and inner as well as outer door handles are available individually depending on the series and the side.
Do I also get the matching small parts?
Yes. We carry the matching small parts, guides and fixings for a secure and smooth run of the door mechanism.
What details do I need for a reliable order?
Series, year and the side left or right as well as the precisely desired part of the door mechanism, if needed supported by a meaningful photo of the existing part.
Do you offer reproductions?
Yes. Alongside original parts we carry high-quality reproductions in good quality, such as locks, door handles, window regulators as well as matching small parts.
