Bought a 72 Custom Camper yesterday. Question.

[Ozark Tim]

I bought a nice 72 Custom Camper/20 truck yesterday. It is still the original Med. Bronze paint with white top. The 350 was replaced with a Goodwrench a few years ago and whoever did it did me the favor of transferring all the original engine brackets etc. from the original motor. Thank goodness!
This truck really needs a good cleaning up more than anything, but it will need the rockers replaces and the rear bab supports are starting to go away. Beyond that it was a real find.
Does anyone know how the Dana axle's are geared in these trucks? I am sure they are at least 4:11 or deeper.
What did this Custom Camper option actually include? If anyone has any info on these it would be greatly appreciated as it is the first one I have had other that a slew of 10 series trucks.
Thanks, OT
