Bucket Seats

This has probably been asked 1000 times. Are the seats the same from the B and E Bodies as the ones for an A Body? I know the tracks are different. Or will a seat from a B or E body work? I want to change my front bench to buckets. I've looked at aftermarket seats, I'm sure they are nice but don't really seem to look right. Any one know of something that looks factory that would work decent.

Thanks for any help
