Re: FSJ Tow Rating
You can regear the AMC 20 model axle to what ever ratio you want ( but you really need to do the front also!)
A dana 60 would be nice, one from a late 80s J truck would probably fit, its a bit wider ( 5-6 inches probably) and you could get the matching front axle too!
I think Id just regear, Get the biggest tranny cooler you can find, make the tranny work right, the kickdown has to be set just right or even a little tight ( very positive shifts) to make a 727 live especially with 2.72 gears!!..
the towing packages on these trucks were : mirrors, hitch, tranny cooler, lockup torque converter DELETE option, 3.31 gears
so if youve got 2.72 and a lockup converter itll be pushing it!
