This project started life as a 1995 993 C-2 cabriolet. I purchased it as a "salvage title" interior fire/burn, and parted it out.

We stripped & sand blasted the tub, seam welded & caged the chassis. We then gave it the Zinc acid etch sealer. We fitted it with the 993 GT2 glass body package, our little twist was the addition of the cab./speedster profile. We have designed and fabricated...
