Hey guys.... I have had a 70 3/4 4x4 chassis here now for a while and I am trying to figure out if there is anything special about the 70 4x4 items on the truck. It seems to me as there were as it was a strike year.... Im thinking thins like the transfer case lever, transfer case crossmember, sm465 shifter, and some of the frame/spring "things".... am I way off base here???? Is there anything special about it??? I just dont see to many 70's running around and I know my 70 SWB 4x4 is kind of a rare bird.... any help is always appreciated...

All i can think of is the 70 front end was first year for open knuckles and last year for drum brakes. Mid year they switched to a wider rear end.
I think it was also the first year for an auto trans in a 4x4 other than the blazer.
Hope that helps
