I snagged the third member off eBay. It has the Daytona pinion support and 3.25" carrier bearings for the 35 spline axles. I used a Moser 1350 yoke, Strange spool, and a set of 4.30's when I set this up a couple of years ago.
This will likely get changed as the new engine will make a trainload of torque. The original build plan included a stroked 318 (390 cubes) which I sold to a friend for his dirt track car.
