Is there a difference between the 66 and 67 bucket seats out of a Barracuda? I pulled my bench seat from my 67, and picked up some buckets that were from (he thinks) out of a late 66, but said that there shouldn't be a difference.

The bolt pattern on the bottom is about 9" (front to back) on the inside of the seat bolts (toward the trans hump), and about 13.5" on the outside of the seat (toward the door side).

The problem is, the 9" spacing is too short for the raised area on the floor pan. It looks like on my floor pan, there are indentations where (maybe?) bucket seat holes would go (?), but they don't really line up with the bolts on these seats.

Anyway, are the 66 floor pans different? Would 67-76? a-body bucket seats have a different hole pattern than a late 66? Any advice?

BTW, if I put the seat forward/rear adjustment lever facing the trans hump (the 9" spacing bolts toward the door), the seat would rest on the raised part of the floor.

Wow a question I KNOW the answer to....

While the '66 and '67 buckets look VERY similar in construction they have a few minor differences which make some of the trim different; the back pieces I think are the same, but the side pieces mount in slightly different locations; not sure if this would effect the functionality, but it would not be correct.

Now for the seat tracks - they are TOTALY different. The '66 has fully adjustable tracks you can adjust seat hight, slope (although u had to use a socket); but the '67 were fixed and only had adjustment to go back and forth.

Also the bolt spacing is much closer on a '66 then the '67+

So the seats "should" work but the brackets will not. I think the spacing on the seat side of the bracket is the same, it is just the floor board side; so you could make a bracket to use the '66 upper bracket and a piece of angle iron or bent sheet metal to handle the lower (floor) side.

Good luck.

I can get you pics / dim of both if you need them.

BTW: if you are going from bench to buckets you need the welded on bracket which braces the floor for the buckets.

Someone on ebay was selling them, but I am not sure who it was... - they are simple to make anyway.
