Re: 73-75 vs 76-77 bucket seats
Yes 73-75 foam is different shape then 76-77. Not sure if actual frames are different but I do know one difference is gonna be the rear bolt hole spacing is different, 73-75 is spaced at 3.75 inches and 76-77 is spaced at 5 inches. The only time this becomes an issue is if your trying to set up the seats in a truck with truck brackets. If your using k5 brackets to go into a blazer than it doesn’t apply as that 2nd inner bolt hole isn’t used. Besides that I believe the seats are identical
What exactly are you trying to figure out to do? If you have a set of 73-75 seats and want to trade for a 76-77 set I have 3 nice pairs.
