My son just bought a 1985 K5 and the rear seat is missing the brackets that help bolt the front of the seat to the cab. Looking for parts and/or drawings so we can fab brackets. Thanks

 

If it is a fold and flip rear seat the seat itself will have the brackets that sit flush with the floor and are bolted down. These flat brackets are spring loaded and help the seat stay in the upright position when folded up.

 

You are right - everything needed was there after all. Found the two grade 8's and shoulder bolt in the console. Thanks for the help!!
