Bench to Buckets...need help!!!

The odd thing is that my passenger side floor is shaped just like yours, according to your website. Hopefully the passenger side will fit fine. They specify the brackets are for 67-75 only. NOT '76...so I am wondering if I have a late 75 model with a 76 body? That would be just my luck. In the above pics the bracket is lined up perfect on the inside dimples. I would need to shim the outside by 1.25" on the rear tab, and about the same on the front. I think some square box channel will do the trick.

Seat height will be the deciding factor. The seat is designed to be mounted at different heights to the bracket, so I think I can make it work without too much work.
