to all you suspension Guru's:

I sandblasted the crossmembers for my truck 1 is a late sixties drum brake crossmember the other is a 71/72 disc brake crossmember I was planning on just swapping the disc brake stuff over to the drum brake crossmember because it is in a little better shape.

Now the Question the 90 degree bracket that bolts to the frame members are different thickness metal (drum .170)(disc.250) does this make any difference to the final set-up I would assume the thicker of the 2 is the strongest?

So should I just burn out the rivets and swap these brackets also?

Thanks for your replies!

you can just grind off the cast stop on the 71/72 spindle to get the turn radius back--and leave the late 60 lower A-arm as is

I think you misunderstood the post I am refering to the bracket that bolts to the frame where the cross shafts are mounted to.
I'll try to upload a pic.

If you're going to use disc brakes, use the 72 crossmember. The little tabs on the crossmember for the brake lines are on the front on a 71-72 crossmember and on therear on the earlier drum brake crossmembers. This complicates the brake hoses. If you use a 71 or 72 crossmember, you can simply run stock disc front hoses and not have to make adapters or run new lines.
