Some additional pics:
88 Chevy bench seat and stock 88 brackets in 49
How they sit on the floor, I'd say about perfect
I used one of these on my dad's Chevelle, and it was pretty slick. I priced out the heims and then tried to figure out how many times it would take to get the "lever arm" length correct on the tranny, and decided it was better to spend $50 on Amazon.com and get this. The "lever arm" is infinitely adjustable, as well as splined for 360* of indexing. Very nice piece for the price.
