i have a 80 dodge 1/2 ton pickup with a dana44 front end. ive been looking at some trac lock units out of 44's in jeeps to put in my front end. as long as the splines and gear ratios are the same is this possible? i plan on taking my ring gear off and putting it on the trac lock unit. several of them on ebay, im just trying to get informed before i purchase.
