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, Tan and Light Neutral

Original Patterns:
Our convertible tops for these cars are made from original dealer patterns. They are not "copies of copies." We offer original replacement Stayfast canvas fabrics.

Fabrics:
Canvas was the original dealer fabric. Stayfast canvas has an elegant canvas outer layer and a butyl rubber central core. You can read more about the fabrics via the "Help" link at the top of this page.

Installation:
This is a classic two part top. You can read a thorough summary of the construction and installation of two parts top via the blue link below. Installation requires stapling or tacking and the use of contact cement. There is no sewing required. The full two part top manual, together with careful disassembly will direct the patient do-it-yourselfer through the removal and installation of a new top.

Tech Support:
If you purchase one of our tops and require technical support, it will be available at: techsupport@mtmfg.com. We will try to assist with all questions relating to installation.

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

Tack Strips:
Tack strips are varathane strips that receive the staples or tacks that hold the top to the front and rear frame bows. Tack strips attached to the bows should last through two tops. Replacement strips are available separately, or packaged within our specials.

About Boots:
Boots are available in GM leather grained vinyl. Boots are listed under "Accessories." Please view the boot swatches via the link shown at each boot listed and jot down your color choice. Order as many of your original boot clips as needed.

Tools:
Staples and contact cement are available. Please select 'Accessories and Tools' which is in the top line of the menu at the home page.

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.
