dana 44hd parts interchangability

[shelby987]

Ok, I have posted a topic regarding brake repair, and the suggestion was made to upgrade to disc. brakes on my truck. My problem is finding parts for the dana 44hd on a 70 3/4 seems impossible....the lock out hubs alone seem impossible to find (yes, the truck currently runs full time engaged hubs....manual hubs would be really nice!).

Question is this, what do I need, and where can I find it....I need interchangability information....the yards near me carry NO vintage chevy parts....what years can I pull disc spindles, calipers, backing plates, and caliper brackets from for a 3/4t? Also, I would like to know what years I can pull a power brake booster....and possibly a proportioning block from if I end up doign the disc. brake swap.

oh yeah, and while I am asking....what years can I pull these hubs off of? (I am assuming 67-76 as all the hubs I find only fit from 77-87......but you know what happens when you assume).

Thanks
