Jon's tub sounds like a good one if you choose that path.

Keith wrote "start with a 964."
- The 964 tub is a LOT stiffer than the true 911 tubs. A big bonus is that the tub itself (stripped of everything else) is just 40 lbs. or so heavier. So you get a lot for a low wt. penalty. The 964 will likely cost more tho and will entail more work to convert, incl. the interior.

Keith -- if you are converting a 964 to an early car look low wt. racer, could you start a thread and post pics and details? We don't have much on that process documented. Pdoc's is the only one I recall.

here you go
