sorry ron. i know what a spool is. i wondered what "brand name" [strange, moser, etc.] it's early in the morning [for me anyway......eyeballs not working,brain feeling crankity, etc..........]
the reason i asked, on my hump, the spool in the dana is a strange unit. i'm not sure, but i think i remember[?] something about a spool made that accepts a "factory" 3.54/4.10 gearset as well as a 4.56/488 aftermarket set. something about not "needing a spacer" or something. anyway, i was wondering if you could maybe measure the distance from the bearing seat to the ring gear mounting surface & the approximate thickness of your ring gear ? oh, by the way, yesterday i finally had enough ambition to fiddle in the garage. i took a jack & spread the sides of the box out about 1 1/2" & lowered the truck down another 2". looks a ton better now ! i'll try to get a couple of new pics today or tomarrow.....
