Hey Boostmaster
What every happened with the seats?
Im in the exact same boat with my 64 tempest and split back front seats. Its either use SMS and spend about $2K or use the PUI stuff that would not be correct for the model. Nothing in between.
I looked up Al Knoch.

Impressive video on the home page but he only does Corvette stuff.
