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 convertible tops are made from original dealer patterns. We offer the replacement tops in original pinpoint vinyl fabric and in Haartz Stayfast canvas. Both of these toppings were featured originally on these 1954-56 convertibles. Canvas was the more frequent original topping.

Fabrics: Pinpoint vinyl is a classic topping. It has tiny hemispheres as the surface texture. Haartz Stayfast canvas is a three layer fabric with an elegant canvas outer face. The bonding middle layer is butyl rubber which gives the top maximum durability.

Rear Window Options: We offer a rear window section (called the "curtain") with a zippered plastic window. You have the option of selecting this convenient window, or else opting for a solid fabric rear window section. In the latter case you would cut an opening and install a window frame and window that you obtain. Please specify which "curtain" you prefer (zippered plastic window or solid.) Make this known in the checkout message box.

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. The installation is, our experience has shown, within the capabilities of the patient and handy first time installer. Stapling or tacking and the use of contact or neoprene cement is required. There is no sewing. A 22 page 8 1/2 x 11 booklet describing classic two part top installation is listed with "Accessories." Only stainless steel staples should be used in any top installation.

Tacking strips: Much of the installation involves tacking or stapling. 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. Rebuilding the rear base line tacking strips requires grafting tack strip sections of suitable dimensions and we would cut and ship per your needs for that purpose.

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

Top Boots: You have the option of using a top storage boot. Our boots fit as originally designed. Boots are listed with "Accessories."

Installation manual: The manual for classic two part tops is summarized at the link below. If you want help making this decision, please read the summary manual via the link below.

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.
