Installed some seats from ebay in my car yesterday (330 w/shipping), well my father and I installed the seats. The brackets you get from Summit, American Muscle, and or ebay are flemsy at best.
Went to Holcombe Motorsports (160 w/shipping) and got there Poly seat brackets. Those are made for the Poly metal seats, most used for drag cars.
Had to buy steel bars(3 feet a piece) from Lowes (17) , put holes in the bars and bolt on to the bracket.
My bucket seats sit high and leaned back. Hugs my buns for cornering.
Installed a Harness bar(ebay 127), and Man what a difference in the chassis when I'm turning, didn't realize how really flemsy the Mustang chasis was.
If someone can teach me how to put pics on a thread, there would be some pics of my car and the install, (which was a pain.)
