ID this bucket seat

I only looked until I found a close match. You can go through the whole library at HH if you have time? Look in the trim books, interior types are also shown in the fleet order books & occasionally the data books.
Hi Barry,
I spoke with legendary and sent him photos, which he also confirmed that the seat looks odd. It is his thought that somebody maybe had a local seat shop make a cover for just the seat and just tried to replicate the top. But he also did say that as far as he could tell, the correct covers will just fit right on these seats no problem and he also said if it was an abody back and an ebody or bbody bottom frame, they probably would not bolt together as they do? Does that make sense
