Ok here goes
seat back
21" tall
19" wide
3"? thick
It's hard for me to determine thickness because my seats are so worn and mashed. But I'd say about 3" or so and the center area where the tuck and roll is, is probably only about an inch guessing from what i see inside them through the holes in the middle to the outside edges of the center section.
seat bottom
21" at the widest
19" at the narrowest
21.5" -22" deep the passenger is deeper than the driver side so roughly in the same area as the mustang.
3" Same as above statement.
So looks like they are basically the same size. The only main difference is the shape of the foam. I think the '65 or 64.5 stang has the same 4"approx bolster around the edges but not positive. Trying to remember what my sister's car had. Some only have the "bolster" on each side. Too bad we didn't know someone with the foam for both gal and stang to put next to each other. I'm sure the dealers of this stuff wouldn't want to do it.
