Buick Roadmaster 76C & Super 56C, 1942-48
Convertible Top and Convertible Top Parts

Buick Roadmaster & Super Key Features:
  • Quality: Made to original specs, 100% fit guarantee.
  • Original Configuration: Two piece top, top section and window section. The window section can have a zippere plastic window or be a zippered two ply blank section (for those with access to glass rear window frameworks.) Molding for over rear section and chrome tops supplied.
  • About 'Blank Curtains: If you have a glass window assembly for installation then we can offer tops with double thickness fabric "blank curtains" to accept your window.  
  • Original Factory Materials: Haartz Stayfast Canvas in black or tan (over black or over tan) and light neutral over tan; Haartz Pinpoint Vinyl in black or classic white.
  • Shop with confidence: 6 year manufacturer warranty.
  • All seams are doubly electronically welded and sewn for added reinforcement. Convertible top fabrics are mildew & mold resistant, and UV treated for color fastness. Plastic windows are DOT rated heavy 40 gauge thick vinyl.

    Note: Early convertible top frames have wood "bows" to receive the attachment staples. A good 'boabuilding' woodworker or cabinetmaker may be able to restore your wood bows or fabricate replacements. Installation steps are very similar to those of later tops using tacking strips embedded in the bows. So the two part top manual will help direct restoration.

    Note: No cars were made during the 1943-45 war years.
  • Hydraulic Components: Hydraulic cylinders, motor pumps and hose sets all available and in stock.

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 any 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 8 1/2 x 11 book is 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 ot can be measured with the old top on the car (as illustrated.)

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.

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.
Warranties outlined here are only applicable for products installed by a professional trim shop or professional upholstery shop. For Convertible Tops, and related products, the manufacturer will void the warranty for any product that is not professionally installed; manufacturer defects are covered by the warranty in such cases. The manufacturer is not responsible for damage due to improper installation.


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