What is involved when initially installing the Smooth Line Hardtop?

Smooth Line Hardtops are an easy, simple installation for the average DIY car enthusiast. All of the hardtops come with all the necessary rubber gaskets, moldings, windows, latching hardware and written installation instructions. There is nothing extra to buy. There are no non-reversible modifications to your car.

The convertible top stays in the car in the down position. In general, it may be necessary to install two brackets for the rear latch points (no hole drilling). From that point it is a matter of positioning the Hardtop on the car and latching it down. Sometimes adjustments to the Hardtop are necessary to suit the differences in your car and are covered in the provided instructions.

Before starting we highly recommend that you read the instructions and become familiar with the details of the installation.  If the installation seems to beyond your ability or level of patience, have a competent body man or mechanic properly fit it to the vehicle. It is not difficult and should take less than 2 hours for the initial installation.


Once it is fitted, it can be painted.  Window, rubber seals, and trim moldings are installed after painting. For specific details, important instructions are located on the specific Hardtop webpage in a PDF format. Smooth Line Technicians are available to answer any questions. READ THE INSTALLATION INSTRUCTIONS!

What is the number #1 cause of installation problems?

Not reading the installation instructions! The #2 cause is not following the instructions. At  times, some experts claim to have years of experience in everything, and may have. 

However, most of them have never installed a Smooth Line Hardtop. Smooth Line Technicians who have installed hundreds of our Hardtops are only an e-mail away.

If I have questions about installing the Hardtop once I receive it, what can I do?

Thousands and thousands of Smooth Line Hardtops have been installed over the years. Everything is checked with jigs or actual vehicles before it is shipped to insure the proper fit to your vehicle. We recommend that everyone, including trained body men, read the installation instructions thoroughly before proceeding to the actual installation. Identify all of the hardware, moldings and weather seals.

You likely won’t have any questions if you follow these guidelines. However, if you do, please contact our tech people by email who will help get you on your way. E-mailed digital photos will solve your problem quickly. We strongly recommend fitting the Hardtop before painting.

After the initial installation are Smooth Line Hardtops easy to put on and take off?

Yes! Smooth Line Hardtops are very easy to remove and reinstall. They are also easy to handle because they are light weight (35 to 50 lbs.)  and generally tools are not necessary. Just a twist of the knobs will loosen the Hardtop. In just a few minutes the Hardtop can be on or off your car.

What do I do with the Hardtop when it is not on my car?

It is important to store the Hardtop so that it is safe and it not subject to damaging the finish or the rubber moldings.

What are the benefits of owning a Smooth Line Hardtop?

 

  • This is the last top you will need to buy!

  • Head turning looks, thumbs up approval – Turn your roadster into a GT or a super coupe with a performance attitude

  • Peace and quiet – great for long trips, conversation or good music

  • Dry – no more water leaks

  • Security - eliminate slashed convertible tops - less chance for break-ins

  • Preserve the convertible fabric from the elements or vandals

  • Drive on the track without the need for a roll bar (check with your track)

  • Aerodynamically cleaner- Better fuel mileage

  • More fun to drive- Like owning two different cars

I plan on participating in some events on a road racing course.

Most tracks will require a roll bar in a convertible for any event while a hardtop is exempt. Check your local rules. For the serious competitor a Smooth Line Hardtop will help stiffen the chassis, aerodynamically cleanup the car for a higher top end, while quieting down the wind and outside noises allowing for more concentration on driving, all resulting in lower lap times.

Are there any advantages in drag racing?

Again check your strip. Most drag strips require a convertible to be equipped with a roll bar or a hardtop. Generally speaking convertibles are limited to a lower speed than hardtops. A Smooth Line Hardtop can help you enjoy the full potential of your car. For the serious competitor a Smooth Line Hardtop will help stiffen the chassis and aerodynamically cleanup the car for a higher top end.

Is a Smooth Line Hardtop a worthwhile investment?

Absolutely!

A Smooth Line Hardtop is the best accessory investment you can add to your car. Besides the payback of your personal enjoyment, your car will continue to look good, adding value to your car at resale.

A worn, ragged convertible top will disproportionately devalue your car, and worse yet, a leaking convertible will destroy your car!

This is the last top you will need to buy!

A Smooth Line Hardtop can also be easily removed and sold to another car owner because no modifications were required to install.

As you know, most add on accessories are non reversible and add very little to your car’s value. A Smooth Line Hardtop is an exception!

What other upgrades are available for Smooth Line Hardtops?

There are six upgrades available:

  • Exterior Material Upgrade For those who would like a contrasting color or don't want to paint we offer a choice of Factory installed premium vinyl exterior coverings. This gives a very soft, subtle look that is not overstated. Available in Black, Tan, and White. Flat Black Finish, and Carbon Fiber Texture.

  • Interior Headliner The headliner upgrade is 3xs thicker compared to the standard Grey headliner and is available in Black or Tan. This offers improved interior sound deadening and insulates the cockpit even better. (See artical )

  • Rear Window *The rear window upgrades offer the choice of Tinted Plexiglas, AS 2 safety glass (OEM tint) with defroster grid.

  • Bright Trim PackageCreate the complete look for your classic with the addition of bright chrome like trim moldings for the leading edge, side windows, rear deck, and rear window surround. Looks better than the way the factory would design it. Compliments the existing bright work on your vehicle for the perfect finishing touch. Moldings are furnished with 3M acrylic automotive tape bonded to the back side and are easy to apply for a permanent installation after painting.
