Fibreglass roof

Ive been searching for an economic solution to get a roof on my 930,

Car in Question is a 77 930 and obviously it originally left the factory as a hardtop

A PO converted it to a Cabriolet in that conversion steel strengething has been run through the car in order to maintain rigidity whilst the roof was down,

I have since removed the Cab roof and all its mechanisms leaving a roofless car with the intent to install a hardtop roof, while ive found a few roofs at good prices they have all been overseas and as such the freight charge runs into the thousands which makes it too expensive,,

I may have found a solution but dont know if it will work,

Ive found a Fibreglass roof replacement for sale, a photo below shows the type it is,

will this work on a hardtop converted to cab then removed again?

My worry is installing the glass as it is heavy
If i get this will it bond ok? plus ill need to bet the side pillars,

Photo shows part and next photo hows car as it stands today

Thoughts and ideas as always will be most helpful appreciated and probably argued with at some point

Im urgent to get something done as i cant drive while its raining

The donor



The patient

roof

Hi I have molds for the speedster hardtop and hump I did have this mold years ago lent it to a guy and never got it back .. I have also got a roof of a wrecked car and had it welded on but this is a massive job.. I can put you on to a guy here in Melbourne that will have a roof if you want to go that way..Paul

Could fiberglass provide the structural solidity of the original steel top?

If the vehicle came from the factory as a cab(and has all the internal structural upgrades), I would see no problem. But if as a coupe, the top was chopped off, and now a new top replacement being fiberglass as you suggest...that might not
work so well.

PM Jim2. He recently converted a cab to a coupe.

He used 2 roofs to do this.

I do have some tubs that are both coupes but I'm not sure I want to cut them up yet. One of the Porsche wrecker must be willing to cut off a roof for you.

I wouldn't do a f/g roof for a street car unless you plan on putting in a full cage. Not to mention I doubt you will ever get the roll up windows to seal, or a rear window to fit correctly. I'd contact a Porsche recycler and see what they charge for the roof clip and rear glass. Have a shop weld it in with the car on a jig. I use to buy Porsche sections from Parts Heaven for my bus project, not that expensive.

Rob, go for a steel roof from a donor car.
- if you could find one without a sunroof, that would be a bit special.

Just finished on my 944t racer a conversion from sunroof to non-sunroof, using a donor car roof.

Explored all options carefully, including fibreglass, kevlar, carbon, steel.

Steel roof conversion was a lot of work, but it is rewarding. Now every time I look at the steel roof, feel lucky I made the right choice.

You will not regret a properly done steel roof.

I jumped out of my willies but turned out it was from a 996 2004 model so it wont fit ..Would have been perfect i could have cut the roof and sold the rest to pay for the cost of it..'
