Weatherstripping | Cleaning & Protectant | Important Information
Fabrics:
The original convertible top fabric was pinpoint vinyl. Original tops were made in three layers. This three layer fabric is equivalent to the modern "Eurotopping Vinyl." Do not confuse "Eurotopping" with "extra heavy duty" and other terms applied to two layer vinyls.
Eurotopping and Haartz Stayfast canvas are true three layer topping fabrics. We also offer this top in less expensive and much more common regular Haartz Pinpoint vinyl. Both pinpoint vinyls have indentical surface finish. Classic Two Part Tops:
You can read how these tops install via the link to our manual summary below. The full, detailed manual is included with our top packages or you may purchase it separately (see "accessories")
If you are comfortable renting and using an air driven staple gun (must use stainless steel staples) then you are a good candidate for do-it-yourself installation.
Tack Strips:
Tacking strips are embedded in the header bow and the rear top bow. They receive the installation staples or tacks.
Pads:
Pads are vinyl clad foam sections that install under the top and build it out.
Boots:
If you desire a storage boot we strongly recommend using one of the modern boot vinyls. These have a slight "give" or stretch which makes them ideal as boots. Topping vinyls will be stiff and unwieldy as boot material.
Hydraulics:
We now stock hydraulic cylinders, motor-pumps, and hoses for your convertible tops. All are made to OEM specifications. Each can be ordered separately; however, when ordering hydraulic cylinders we recommend replacing both. The chances are that both hydraulic cylinders were manufactured at the same time: if one is on its way out the other may follow. If the top is raised and one hydraulic cylinder is working harder than the other the result over time can lead to a slightly bent convertible top frame. The replacement of both hydraulic cylinders will ensure that the top raises and lowers symmetrically.
Systems for this car take Automatic Transmission Fluid (ATF) and have a 5 year warranty when used with this fluid. Brake fluid should not be used as it voids the warranty. We also offer an installation manual when ordered.
The 12 volt motor-pumps include a mounting bracket with rubber grommets to reduce vibration.
We also offer a rebuilding service for motor-pumps. Not all are repairable, but it is less expensive to have one rebuilt than to buy a new one. The motor-pump would need to be sent to us for evaluation. Hoses come with all new fittings and are made specifically to fit your car.
Parts in this category (Pontiac Starchief & Bonneville) fit cars for years: 1955, 1956 and 1957.
We a now pleased to offer hydraulic cylinders, hydraulic motor pumps, and hydraulic hose sets.

Look for extra savings on weatherstripping seals kits.
