Newby?? 69 to 72 A-arm/K-member swap ???

[jtmiller92]

Wasnt sure how to word the title but here goes. What are the differences if any in the upper and lower a-arms on 68-69 drum front ends and say a 72 disc upper and lower a-arms front end? Also are there differences in the K-member/Engine Crossmember? Will they all interchange?

The Reason for my Qustions are I have a 72 SWB TRuck I am restoring but the K-member and A-arms are poor condition, alot of rust in them. I have a good 69 frame that was restored sometime in the past and the upper and lower a-arms are in great shape along with the k-member. I will be using 72 Disc brake spindles if that makes a difference. I would use the search function but its not working. Thanks, jt
