so I was over at my used 67-72 truck parts suppliers barn the other day and we was just standing there staring at both a 67-70 crossmember and a 71-72 crossmember and the only difference we could spot was the extra brake line brackets on the front of the 71-72 crossmember for the disc brakes, is that the only difference

Joe does drum to disc brake conversions by unbolting the 67-70 crossmember with all the drum brake control arms and spindles on it, and just mounts a 71-72 crossmember with all it's disc brake control arms and spindles in it's place and it just bolts right up

I told him about lolife's (Keith's) write up and how he could just swap out the ball joints and tie rod ends
