Original Patterns: Our convertible tops are made from original dealer patterns. We offer the replacement tops in original pinpoint vinyl fabric in both regular Haartz pinpoint vinyl and Eurotopping pinpoint vinyl.
Fabrics:Eurotopping pinpoint vinyl is made with a thick butyl rubber central bonding layer. This process is the same as used in Haartz Stayfast canvas. The process makes these fabrics the longest wearing. Please do not confuse true Eurotopping with claims of "double texture" or "super heavy weight." Heaviness, by itself, does not confer advantages over lighter flexible toppings.
Regular Haartz Pinpoint vinyl has the same outer and inner layer as the Eurotopping but does not have the butyl rubber core.
Zippered Rear Window: As original in these classics, the rear window is zippered.
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 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.
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. Rebuilding the rear base line tacking strips requires special instructions and materials which we can supply. Please inquire.
Top pads: Top padding "builds out" the top. Pads can last through two tops but should be replaced if of suspect condition.
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 5 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.
Parts in this category (Oldsmobile Super 88 & 98) fit cars for years: 1957 and 1958.
