Okay andrew, I have a 1990 Dodge D60 it came with the center drop set up. 1 soft line from the frame with the T block going to the L & R hard lines that stopped at the knuckle. Then there was a 10" soft line to the caliper. The soft line will work on a 10B and should on a D44 too. You will need to make your own hard lines as the dodge axle is a little narrower than the GM axles. Use the longest GM rear drop line you can find (I have a napa # around hear somewhere) and wala. Keep a center mount limiting strap for the ocasional jump or two and you are good. I don't know how the proportioning (sp) block on the x-member fits in this though. Rob, or somebody else if they are reading, will have that answer.
