New Edition!!!
Convertible Top Guys' "How To Remove and Install Classic Two-Part Tops."

This 40-page, extensively illustrated how-to manual walks you through removing and installing a two-part convertible top. The manual applies to almost all American convertibles made before the year 2004, and some foreign cars, too, like Celicas and Saabs. This is a bound 8 1/2 x 11 book; designed as both a tutorial for first-time installers and as a step-by-step manual for these convertible tops. Generally, all that is needed and not contained is the "bow height" which is the setting of the rear top frame bow for your convertible. This is available from any top distributor.

What skills are required ? (1) The ability to drive staples into bow frame tacking strips (2) The ability to orient fabric sections to the frame and apply with contact cement. (3) A systematic and careful personality ! (There is never any sewing required.)

Note: Very early cars (forties) had wood bows and installers will have to adjust processes for stapling to these bows instead of tacking strips in steel bows as described in manual.

Important Information

Original Factory Color(s): Black and GM White

Original Patterns:
These tops are made using original patterns that the factory obtained many years ago. They are not copies of copies.

Fabrics:
The original convertible top was made of canvas. The modern anti-fade Haartz Stayfast canvas is the best topping fabric for this car. Haartz pinpoint vinyl is also an elegant classic fabric. It is less expensive than the Stayfast canvas.

Rear Window:
We offer a plastic rear window section and also a "blank curtain." The blank curtain is for those with access to a frame and glass that will be installed into the blank rear section (curtain.)

Two Part Tops:
This is a classic two part top. We are offering both sections together, for the typical restorer (either with the plastic rear window curtain or the blank curtain.)

Please inquire if you wish to order the main top only, or the curtain only.

Installation Manual:
The two parts of the top are integrated during the installation. The process is summarized in the blue link below. The full top install manual is available; listed as an accessory.

Pads:
Foam pads, encased in fabric, are installed under the top and "build out" the top. Our pad set comes with the longer and the shorter (rear) pads.

Custom Order:
These tops require about three weeks before they can be shipped.

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 1 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.

CONVERTIBLE TOP FABRICS
Almost all manufacturers use Haartz fabrics. They may specify "heaviest weight" or "original replacement" in ways that seem reassuring. But they do not really tell the whole story. Please bear in mind that two things dominate, by far, the quality issue: (a) the manufacturing quality control in the factory that makes the top and (b) the care and thoroughness of the installation. There is a trade-off in weight: heavier is better for resisting tear through, but lighter is better for flexibility and abrasion from within that may arise from movement. Almost all our tops are a flexible medium density (36 oz.) fabric. Heavier is not better in most cases. Where it is, because of the top design, we will say so and the top will be made of the heavier vinyl.


Parts in this category (Buick Roadmaster 76C & Super 56C) fit cars for years: 1942, 1943, 1944, 1945, 1946, 1947 and 1948.
