I'm pretty sure of the answer, but I just wanted to double check.. First, I've got a '90 K5 which has 30 spline 10-bolts front and rear. After doing some research it seems as if the 30 spline front 10-bolts were only offered from around '89 or '90 until '91 in K5's and Subs, so needless to say they are a bit hard to find in junkyards. I want to find some used front axles to carry as spares until I can afford the chromoly ones, so I was thinking of getting some 44 axles. Project Stinky in Fourwheeler magazine did this and supposedly they work okay.....anyone have any additional experience on this?? Secondly, do the spindles, hubs, and rotors interchange between a Dana 44 and 10-bolt (6 lug Chevy of course)?? I'm pretty sure the hubs and rotors will work but I'm not positive about the spindles. Again, this would just be to carry as spares. I thought I could just buy a complete 44 and strip it down for the parts.
