I Need a Seat
 

working on our 1986 chevy Silverado, want to put in bucket seats, what seat will fit?

The Chevy Blazer and Jimmy from the same era but it will still involve some mods to mount them

Its not so much what seats will fit, but what seat mounting brackets will fit your floor pan. Like Glenn says, try and find the brackets from a similar truck as yours.....Almost any bucket seat could be bolted to those brackets with a minimum of fabrication.

I believe most 80s GM trucks will have the same floor as yours....lots of them in the boneyards
