No argument. Just adding an option. And the Cherokee is a better option if you want a shorter gear, too.
There are 2 FMJ's in the local pick your part yards as of weekend before last. One is an M-Body and has the 7.25" peanut rear end, but the other is a station wagon and should have (had?) an 8.25". Buddy got the spindles off the M-Body. So they are still a possibility around here, even if they are far rarer than they used to be.
