BTW-
The advantage to the Mustang II is that there are tons of parts out there for that set up. It seems like everyone carries the rack, springs, arms, shocks, discs, bushings, calipers, upgrade kits, etc... All that stuff will work just as well on a MII from a junk yard or an aftermarket seller.
Pacer and Volare are harder to repair/replace/ upgrade just 'cause they're less common and have been out of production for a long time.
