7.5" 3.73s pulled from??

Going to the JY.  Anyone know what had the 7.5" rear end and 3.73 rear gears?  Aerostars, Rangers...?

Thanks,
Dan

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

The aerostar i got my posi from (5sp w/ tow package)  had 3.53s but I didn't grab the pinion.  If i cant find a 373s i will just get the pinion and put the 3.53s in.  I'll let you know what I find.
