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: Our Buick convertible tops are made from original dealer patterns. We offer the replacement tops in original pinpoint vinyl fabric and in Haartz Stayfast canvas. You can read all about these materials at the "Help" link at the top of this page.

Zippered Rear Window: As original in these classics, the rear window has a horse shoe zipper.

Installation: This is a classic two part top. You can read a thorough summary of the construction and installation of this top via the link at the bottom of this page.

If you are comfortable using an air driven staple gun, and with aligning and gluing with contact cement then you are a candidate for do-it-yourself installation. The full manual has been used by hundreds of first time installers in replacing this classical two part top.

Both Parts Available Separately: If you wish to replace only the window section, or only the main top, the two parts are separately available. Please inquire if you want only one of the parts.

Tacking strips: Much of the installation involves tacking or stapling (there is no sewing involved.) Tacking into the bow over the windshield (header bow) and into the bow over the rear window (rear top bow) is done into special strips embedded in these frame bows. We offer new tack strips for the front and rear top bows. They should not be required until after at least two tops have been stapled to them.

Top pads: Top padding "builds out" the top. Pads can last through two tops but should be replaced if of suspect condition.

Staples and Glue Kit:Stainless steel staples are required for top installation. Our 'staples and glue kit' is listed as an accessory. It is included with our top packages.

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.

Do-it-yourselfers:   Read a summary of convertible top installation.
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.
