For the bench seat....for the most part,yes,it does bolt in,but it doesn't slide all the way forward like the buckets do. When you slide it forward to gain access into the back,the centre of the seat cushion catches on the tranny tunnel and stops it fron going forward very far. It only moves a couple of inches.
I tried it,lol.
btw,those Eclipse seats are so freakin comfortable.
I want to put these in my truck:
1987 Toyota Celica GTS. I've had these in my basement for 5 years.
