I think I might have traced the origionator of Covin builds in SA???
I visited a company called street stuff:
http://www.streetstufffibre.co.zaand spoke to the owner. He stated that they had started to build porsches on beetle chassis way back in the day, and since then he had a contract going with an overseas company to continue to build cars, but the partnership went sour...?
anyway I have taken pics of his shop to show some parts he makes...
converted this 911 and fitted a roof etc...
some other parts:
also check out his other moulds..
there is so many other moulds he has for porsches, such as fenders, widened arches etc...
very nice place this,
wish I had his skills!
