[C10Silverado79]

They will fit but it's not a 'bolt in' swap. I just put a 60/40 bench from a 92 in my 79. I used the seat tracks from my bench and got a 2nd set from the junk yard. The drivers seat left track and the passenger seat right track bolted up right up. I had to make some brackets for the drivers right front and the passengers left (front and back) because of the floor pan. I have some pics but can't upload them right now.

Check out threads on installing bucket seats and you will see a lot of info on making the front brackets or getting them from a donor vehicle.
