The actual dana 44 was available until around 78 in the chevys and later in the GMCs. The 73 and newer axles will have a slightly larger axle u-joint, which is desirable. While finding a 71-72 would be nice, I'd say start by looking for a gear ratio that matches your rear or what you want then go from there. You could broaden the search if you include the 10 bolt available up to 87 or 91 depending on truck or suv. One of the biggest differences would be a metric banjo fitting at the caliper.

Scrap any pre disc D44 unless your doing a 100 point restore. It's not worth the time to mess with if you building a truck to use.
When looking for a replacement get a 74 or newer. 73 and older ran smaller u-joints. I 147 or something. the 74 up 1/2 and 3/4 run a 297. The disc front ends made 70-73 can swap to the larger u-joint axle shaft no problem.

this truck is meant to be driven. they way i figure it, my options are:
1. 74 and up d44 (or d60) 2. find an original 71-72 d44 with front discs. what has to be modified to fit a 73+ d44 to our trucks? spring perches on the axles? etc, what else? i want to keep my 8 bolt wheels. is the track width of the axles different? thanks for all the help!
