I thought I would post this because there seems to be so many inquiries about bucket seat swaps, and the fact that the original equipment stuff is expensive and getting harder to come by.
'88-98 manual seat bases bench and bucket, are comprised of of the same components.The risers are interchangable;
If you have a factory bench, unbolt the horizontal bars that go across the trans tunnel, and you have the riser for one seat.(obviously you will need a shorter spring).
You will need another bucket or bench, riser for the second seat.
As everyone knows, when going from bench to bucket, you will need to drill holes for the inner mounting.
I have owned 4 C/Ks since '88 (88,90,94& 99)All of them had dimples (markings) in the floorpan for factory bucket seat mounts. My '94 suburban had the un-threaded nut and backing plate welded in the proper location beneath the un-drilled floorpan.
Mid size '92-'00 pontiac bonneville (and other GM midsizes on the same platform) bucket seats will bolt directly to '88-'98 seat risers with NO MODIFICATIONS, they both share the same riser-to-seat bolt pattern. These seats are cheap, and plentiful,and come in cloth and leather,recline and power lumbar was avialible.
I purchased 4 seats for my suburban for $100.00
The power seat units in '88-'94 and '95-'99 C/Ks will also bolt directly up to these with no modifications.
Check the pic of my '94 sub. The driver side power unit is from a '98 Tahoe, and the passenger side is my original '94 bench seat riser.
No mounting holes were enlarged,slotted,or modified in any way.
BTW, I find these seats to be EXTREMELY comfortable.
