Want to put buckets in my bench seat car

Either you find a-body buckets with tracks and drill the floor for a direct bolt-in or do a little fabricating. The important thing is to be sure the floor is reinforced where the holes are so that the seats don't rip out of the floor when you least want them to.

I installed aftermarket seats in mine and fabbed some brackets so they could go where factory holes would be.
