Important Information
Original Factory Color(s): Black and GM White

Fabrics: The original convertible top fabric was pinpoint vinyl. We also offer the top in Haartz Stayfast canvas. The fabrics are described, in detail, at the "help" link at the top of this page.

Original Patterns: Our 1958 Impala tops are made from original dealer patterns.

Installation: This is a classic two part top. You can read a thorough summary of the construction and installation of this top via the blue link below. The full installation manual is available under 'Accessories' on this page.

if you are comfortable renting and using an air driven staple gun then you are likely to be a good candidate for do-it-yourself installation.

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 are available separately, or included with our restoration packages.

Top pads: Top padding (underneath the top) "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. Replacement boots are available, under "Accessories." Our Impala boot has non-original snap installation.

Installation: The manual for classic two part tops is summarized at the link below. The full manual (see "accessories") should enable the careful handy person to perform his or her own installation and should be used in conjunction with notes taken during the removal of the old top. Installation involves stapling and glueing. There is no sewing.

Hydraulic System Parts:
We 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 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 will ensure that the top raises and lowers symmetrically.

Systems for this car take hydraulic or Automatic Transmission Fluid (ATF) and have a 5 year warranty when used with either. Brake fluid should not be used as it voids the warranty. We also offer an installation manual when ordered.

Motor Rebuild Service: We can return your existing motor to near new performance with a complete refurbishment. Ship us your motor (please wrap very thoroughly as leakage can lead to post office seizing package.) We will rebuild your motor and return generally within a week of its receipt. You may ship to us with a money order for $150 which covers refurbishment and shipping back to you.

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


We a now pleased to offer hydraulic cylinders, hydraulic motor pumps, and hydraulic hose sets for many different convertibles, they will be listed on your cars page if available. Also, checkout our newly added roof rail weatherstripping seals, front header weatherstripping seals, door weatherstripping seals, trunk weatherstripping seals. Look for extra savings on weatherstripping seals kits.

We are continuing to grow our convertible related products: These include convertible top latches, tonneau covers, relays, switches, rear tacking rails (trimsticks), seat covers, car covers, and carpeting.
