Re: 73-75 vs 76-77 bucket seats

I saw your post on TCKR's thread and thought I would ask here - instead of there - about the differences between 73-75 and 76-77. If you would post some pics of what you got that would be great, there is insufficient info out there regarding squarebody buckets, IMO. What you have could be helpful.

I was lucky enough to score some "medallion" style buckets that I now know are 76-77 seats, but my goal is to reupholster them into 73-75 versions. I am wondering if there is any reason I could not simply refoam and recover them, or if there is some structural difference that means I should abandon this idea.

Besides inner rear rivnut spacing being different, frames should be the same but not 100% sure. So yes, hypothetically you should be able to refoam with 73-75 and use corresponding covers.

Let me know if you try this. I have multiple sets of 76-77 and would like one more of 73-75 style.

If there was a difference in the frame I would think it would be at the tops where on the early style it’ll be more narrow than the later style

Re: 73-75 vs 76-77 bucket seats

I have striped both set down (73-75) and (76-77) as far as I can tell there is no difference in the metal frames. The bolts in the frames line up with my hardware also.

I have ordered 73-75 seat foams and covers but have yet to install.

I can say with a 95% confidence you can make 76-77 seat frames into 73-75 seats. I will add the 5% when they are covered.

Re: 73-75 vs 76-77 bucket seats

Just to follow up with this thread.....76-77 low back bucket frames are basically identical to 73-75 ....I used 73 covers from distinctive industries, 73 foams, and 76 frames.....they look like they are supposed to
