will seats from a 1988 olds delta 88 fit into a 1975 olds delta 88 convertible?

 

i don't think you would run into any problem other than maybe the mounting bracket on the bottom of the seats, maybe you could take the original seat bracket and mount it to the newer seat? just a thought.....



Okay I wen't out and measured my seat for you it's an 85 delta 88 royal brougham ls. Power seats.

anyway the width at widest point on the backrest is 54inches, the width for the mounting bolts from left to right center of bolt to center of bolt is
14 and 3/8 of an inch. hope this helps you.

 

Without modding? No. Plus the 88 Delta is way smaller than the 75, so it would look really out of place
