difference is A,B, and E body seats.

I'm needing to get a set of bucket seats to put in my 70 dart swinger so I can install my console and shifter. It seems like the 70 dart bucket seats are pretty hard to come by and I'm not really a fan of the 73+ seat designs from what I've seen. Some of the E and B body seats look pretty good and it seems that E body seats are pretty easy to find. So would any E or B body seats fit my car assuming I had the correct 70 a body tracks?

There is a MOPAR car show and swap meet this weekend and I'm hoping to find a set. I'm fine with using E or B body seats if they will easily work without a bunch of fab work.
