Fox's
The Ford "Fox" family of cars are the mid size ones such as the 79-93 Mustang, 80-81 Granada, 79-83 Fairmont, 83-86 LTD/Marquis, 79-88 T-Bird/Cougar.
This was the start of "Rack & Pinion" steering, which wasn't available on the Crown Victoria until 19xx!
The 83-86 LTD is often confused with the larger Crown Victoria which until 1983 used LTD in it's name. The 83-86 LTD has a 105.6" wheelbase while the Crown Victoria's is 114.3" & 700 #'s heaver.
What's real irritating is when people say, oh, do you mean a LTD II? The LTD II was from 77-79 and a real "barge", weighting 1100 #'s more on a 12" longer wheelbase of 118". This sounds a bit like my old 63 Galaxie, but it wasn't a barge, maybe a "Yacht"?
The 85 Mustang had a wheelbase of 100.5" & the T-Bird was 104".
