Cabriolet to hardtop conversion
 

This is my first thread and it could leads to some rocks being thrown at me..

So I'm based in Australia and I've been searching for a 964 C2 manual for a while - No luck - there are none available!

There are some well-priced cabriolets around, and the curious one in me got to thinking about modding a cabriolet into a hardtop - given I also want to use the 964 as a base for a backdate ST. In some ways it could be good (theoretically) because the factory stiffening which was done to the Cab's coupled with a 4point roll-bar and strut brace could make a very stiff car to work from.

Anyone seen this - heard of this - done it - avoided it? I'll take advice from all comers.

Relatively easy. Find a complete top- non sunroof preferably, measure, measure again, cut and weld. Make sure you have the car on a solid flat surface and it's perfectly level due to flex and off measurements.
You'll also need couple door glass and frames, quarter windows and back glass. Windshields are the same.
The non sunroof tops are easier because of the drainage holes.

Thats great. Ar the coupe roofs prefabricated with the body or attached onto the chassis? I'm assuming by doing it the way you've suggested there's no structural issues if done well?

I know it's not conventional work in order to get a backdate project up and running but i may just be necessary in order to get a decent base car

Cab RS backdates.....not many around, I would do what I did. Cage it and run it as-is with the back dated body parts.

There's a guy on here who did that. There's a thread somewhere photo documenting what he did, you can probably find it if you search.

Zags in Penrith NSW have done this before:

Thanks Ryan.
McLovin these are the threads I've found: 911-cab-girly-car
and

both with VERY different approaches to solving (mostly) the same problem
