Bench Seat Upgrade

Hi All,
Have the chance to pick up a nice bench seat out of an 88 Chevy pickup and would like to replace the bench in my 1978 Sierra with it. Can this be done? Or is the framework completely different etc. First post here so thank you for adding me!

Re: Bench Seat Upgrade

I believe this thread probably has the best answers for you

In short, you'll probably have to make a new frame or at least do some modifications, but it doesn't look terribly difficult.

Re: Bench Seat Upgrade

I have done this. My wife insisted on a seat with headrests. I found what was the nastiest seat from 89 pickup at the junk yard. The 89 sliders would not work on our floor. (there is much more room between the floor and the seat bottom on the 89) I used the stock 85 seat sliders but had to cut them down as they are much longer than the seat bottom from the 89.

All in all the seat works but I think the 86 had a thinner backrest and longer seat bottoms. However, the 89 foams are more contoured. (almost like bucket seats) If I had to do it over again, I would probably look at welding in the headrest mounts into the 85 seat frame.
