Buick Super 56C & Roadmaster 76C, 1950-52
Convertible Top and Convertible Top Parts

We are pleased to be able to offer accurate reproductions of these tops made with original patterns.

The original Buick super convertible top fabric was canvas. The modern Haartz Stayfast canvas tops capture the original appearance. Tops made from the same patterns but in Haartz pinpoint vinyl are also available.

These tops are usually chosen with a zippered rear plastic window. We also offer the top with a blank "curtain." (the rear window section is referred to in the trade as the "curtain.") the blank curtain tops are made for those who have access to old or to custom made rear window frames which can be stapled into the blank curtain.

Installation: this is a classic two part top. The curtain staples to the bow over the rear window and at the base. Over it is stapled the main top on the rear top bow and also at the header bow. Fabric is also attached at the pillars behind the rear side windows. The procedures for installing these tops are contained in our installation manual on classic two part tops. This manual is best used in conjunction with careful notes taken during the removal of the old top. We do not offer top installation consulting.

Tacking strips: tacking strips are embedded in the front and rear cross bows of the framework. These receive the staples. There is also a set of 'trim sticks' which are the tacking forms along the rear base. New tacking strips are available (see accessories below.)

Our tops come with the required "hide-em" molding.

About our boots: replacement boots are made with modern boot vinyls. These are leather (crush) grain vinyl with a slight elasticity. The "give" in these fabrics makes them ideal for top boots, eliminating the difficulty of use experienced with traditional boots. You may view swatches via fabric links and select your choice in the checkout message box. Boots require three weeks to ship.

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.
