I have a '94 mustang timing cover on my '94 SC with an SC water pump.
Casting numbers are identical for 94-95 SC and 94-95 mustang timing cover, even though the water pumps are different. They are the same cover.
In fact, the '95 ford windstar also uses the exact same timing cover.
94-95 t-bird LX 3.8 and all taurus 3.8 timing cover is different, and doesn't have the mount for the crank sensor pickup, as those models used distributors. 89-93 SC, 89-95 LX, and all Taurus 3.8 use the same timing cover.
You can fit a 94-95 SC timing cover on any 89-current block, but not vicea versa if you have a EDIS (94+) distributorless ignition system.
