Pontiac Starchief & Bonneville Key Features:
  • Quality: Made to original specs, 100% fit guarantee.
  • Original Configuration: Two piece top, top section and window section. Molding with chrome tips for above rear window included.
  • Rear Window Sections: Rear window was originally zippered plastic. We offer this as all clear plastic ("full view") or plastic with lower fabric trim (horizonatl 'feature strip' along bottom/)

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.
 

Restorer's Notes:
The most applicable restoration 'instructions' that we know about
are in the 50 page tutorial/manual on two part tops (see below
under "Installation Supplies.") The examples in the manual are from the sixties
but are broadly applicable.
Installation of two part tops requires confidence with using an air driven
staple gun or our heavy duty electric stapling gun. There will also be
contact cement work

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

Fabrics:
The original convertible top fabric was pinpoint vinyl. Original tops were made in three layers. This three layer fabric is equivalent to the modern "Eurotopping Vinyl." Do not confuse "Eurotopping" with "extra heavy duty" and other terms applied to two layer vinyls.

Eurotopping and Haartz Stayfast canvas are true three layer topping fabrics. We also offer this top in less expensive and much more common regular Haartz Pinpoint vinyl. Both pinpoint vinyls have indentical surface finish.

Classic Two Part Tops:
You can read how these tops install via the link to our manual summary below. The full, detailed manual is included with our top packages or you may purchase it separately (see "accessories")

If you are comfortable renting and using an air driven staple gun (must use stainless steel staples) then you are a good candidate for do-it-yourself installation.

Tack Strips:
Tacking strips are embedded in the header bow and the rear top bow. They receive the installation staples or tacks.

Pads:
Pads are vinyl clad foam sections that install under the top and build it out.

Boots:
If you desire a storage boot we strongly recommend using one of the modern boot vinyls. These have a slight "give" or stretch which makes them ideal as boots. Topping vinyls will be stiff and unwieldy as boot material.

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.
