The controls for the non-sport sears are in the front (at least they were in 93). It is the one on the right in the following pic. AL7 seat on the left:
I was wondering... if you have a bench seat now, do you have the inner mounting studs in the floor? I went from bench to buckets in a 90 Chevy pick up and had to drill through the floor to add bolts for the inner mounting points. The seat frame of the bench went all the way across. I'm unfamiliar with how the bench seat frames are in the Bonnevilles.
Also, the OEM console bolts to the floor and to the floor shifter. You might need the studs that snap into key holes under the carpet. There is a chance I have some from the parts car but I'd have to sort through all of the hardware. If you need them, let me know.
