Clutch for 66 Barracuda Formula S

I agree with 66jim in that you check with a couple of specialty clutch companies. In no particular order, you can call any one of these guys and see if they can help. I could be wrong, but with the correct disc, you don't need all that spring load. In fact, I know that. I've run 9 springs in a 12 spring cover many times.

Black Magic Clutches
Hyatt clutches
Advanced Clutches

I think the Advanced Clutches is Rob Youngblood. BMC is Cale Aronson and Hyatt used to be Tim Hyatt but he passed away and I think his son is doing it now.
