i have to second the vote for the clutch type unit in the auction. However, I think you'd be better off getting an 8.8 pumpkin from a Super Coupe or other V8 MN12. They're not that hard to find and not very expensive. By the time you set up the 7.5 with the gears you want, you could have done it cheaper with an 8.8. The rebuild parts for an 8.8 (gears, traction lok clutch kits) are cheaper than for a 7.5.
