Jeep_Man_401, I think I may have located a 78 HPD60, but this would be the wrong drop for you based on what I have read unless you want to change your t-case (or re-tube). I'll keep an eye out for a Chevy/Dodge for you. These are not that far from me, but they are not cheap. However, they are mostly new, have 35-spline outers, geared, Detroit'd f&r, and it includes some steering parts:
Dana 60 front. 4.88. Detroit. 0 miles on all parts. Completely rebuilt, new. 35 spline outers w/lockouts and drive flanges.
14 bolt rear. 4.88 Detroit. Used, but not a thing wrong with it.
Cross over steering setup. Arm, drag link, steering box, pitman arm. Thinking of going a different direction with the truck, but I can only do it if I sell this first. This is a COMPLETE setup. Located near Yale, MI. $2500
If anybody would like me to look for candidates, PM me with the specific configuration you would prefer. :t:
I'm guessing that the 80-up FSJ crowd wants to stick to the 78-79 HPD60's due to the close match on the perch spacing and inboarded diff (longer driver tube), but later models are fine for people running 4-links. As for the 78-79 HPD44/D60 combos, I find them fairly frequently and they typically have 4.10's. These are nice since they are factory SOA, flat-top, reverse-cut, typically equipped with lockouts, and have dual-piston calipers.
I'll post links to whatever I see that is not feasible for me to handle personally due to distance or equipment limitations. (I'm currently in the market for a better utility trailer.)
