I put a 1969 frame under my 1972 and the only differences were the brake hose mounting points. The front brake hoses are in front of the crossmember on one and behind the crossmember on the other. I chiseled them off and welded them on the 69 frame. I changed the crossmember behind the rear axle for the rear brake hose. I chiseled the rivets off and bolted the new crossmember in with grade 8 bolts. Everything else was a direct bolt on.Hope that helps.
