[C2] Top Questions
Thanks for any info






Not only that but if you leave them down for too long the material will shrink and it will often no longer fit even after leaving it in the sun for a long time. I understand that the fabric rather than the vinyl material is more resistant to this problem.

I live south east of Cleveland, Ohio. I do a lot of C2 tops if you are close by. Where are you located?

Dealing with any rust on the header so you can install the tack strip. Installing the tack strips correctly. installing the wire on binding correctly. Installing the header windless correctly. Installing the correct windless for NCRS judging. Dealing with bent rails and replacing broken or missing rivets.
Just to name a few of the many problems that can occur.
Appreciate your experience, probably saved me a not so nice install.





I am a driver and will enjoy using it in the winter when dry; that is the reason for a top. Appreciate all the comments.
1) the measurements between the bows.
2) the installation of the top to the rear bow. Most people think you start in the middle and you don't. You measure it first then transfer this measurement to the top. Then you start on the ends and work toward the middle. If you start in the middle you'll swear the top is to small which if it's a Knoch top (the only top I will install) it's 100 percent correct in size. So the trick here is to make sure the rear bow is installed on the frame without anything on it. Then take a measurement from the the vertical edge to the front edge of the rear bow. I've posted a picture of this below as well. It's from a 68-75 top but it's done the same way. Then you transfer this measurement to the top with a pencil and you'll install each end about 6-8" first before moving on toward the middle... Trust me the top will stretch and fit but if you do it from the center you'll end up short.
3) the correct equipment and various sizes of staples. I've seen people use swing line staplers to do this installation and that's a huge fail.... we use a fasco pneumatic stapler here when we do the installations.
4) How to get the hold in cord in the rear bow.... I've seen everything from soap, water and what ever to get the cord in but a long time ago Al showed me his trick which was to use regular oil and wipe the cord down with it. If you do this to cord will fall into place very easy, if you don't prepare yourself for a struggle.
If you look at the picture below it will show you the pad installation. I'm working on a help page for the tech site but I don't have it finished just yet.
I think I covered most of it... and this is not to say you can't do it yourself, you just need good equipment and take your time anyone can do it.
If you go to this link you'll see some pictures of a top we installed a few years back. We actually do about 5 of these a year on cars from 58-75.

I used to measure the A to B distance but now I simply lay the canvas over the frame and hold the bead to the side rail right where I want, pull tight towards the rear and mark the end of the rear bow with a pencile.
Also, the pads are the foundation for a great top install. It is worth it to take your time to measure and get all the wrinkles out. I will spend a lot of time on the pads and go over them with a heat gun to get the wrinkles out.
I'm sure you got the point that it is well worth it to find an experienced top installer. Even if you have to travel.
