1987- 90 seats the same as '91 - 93 except headrest?

Hi, Are the early fox GT seats the same as '91 - '93 except for the size of the headrests? I have a pair of the shorter ones (91-93) the seats are shot. I am looking to recover a set in the Mach 1 style and like the lower headrests. I can't seems to find a nice pair of the newer ones, but a ton of the older? Thanks
 
Fox sport seats came in 3 styles, 87-89 with adjustable thigh support and large headrests, 90-91 with adjustable thigh support and small headrest, and 92-93 with solid seat bottoms and small headrests. Now I would assume the 87-91 seats themselves to be the same, with the only difference being the headrest, but I haven't looked at them side by side to make sure. And of course the kits are sold based on the headrests and seat bottoms, so they keep the 87-89 and 90-91 as separate kits. Maybe call Mustang Parts & Accessories - 50resto and ask them if the 90-91 kits will fit a 87-89 seat if you use the 90-91 headrests.

Good luck!
 
the grey color is a shade different i know that but i am pretty sure the rest of the seat is the same other than the headrest. you might be able to swap your headrest over though
