Yaa my 1994 regular cab buckets look different than snapon's, I think they're the same as 97, they have the fold-down seat in the middle with cupholders and storage in the back. There's also a longer ledge along the outer edge, with the lumbar buttons and such.

I never directly measured it, but my 1996 bench and 1994 buckets seem to have identical 4 bolt-down locations. The bench had the 4 spots integrated while the buckets bolted to a frame that sat in the 4 spots.
Now that I think of it my 1994 parts truck had a bench and I'd swear the mounts were identical to my 1994 buckets as well.
