Nice project! While I've been under an older cckw encrusted with dirt and grease to check out the drive line I haven't got that top view factory fresh perspective of your truck. The mechanics involved of two rear driving axles interests me.
My 506's a bit simpler with only two axles on the truck but being an auger version it does have four drive shafts and lucky for me the last owner kept all the u joints greased. I'm finding on other trucks I have that good non-chinese u joints are getting hard to find!
I look forward to seeing more pictures as your project progresses.
