There are 2 Roadie wagons in a local junk yard (yes JUNK yard, not a salvage yard!). One is a '92 not sure of the other, but both are pre 1994 models. Anyone know what final drive gear ratios were used in a '92? The rear in my '96 may need to be replaced and figured since the junk yard is only about 5 miles from my house........
Not overly concerned if they are posi type rears as mine isn't posi anymore.

2.73 for regular one, 3.23 for tow pack.

GU5 is the RPO code for the 3.23 gears, and of course, G80 is the posi.

I either case, you will need your PCM reflashed for the new gears so your shift points are correct.
