Cpp has the adapter which is just the adjuster sleeve with two different size thread/bolt patterns on each end. (I have an opinion about CPP but would rather have you try deal with that on your own)

Recently companies have introduced a 3/4 to 1/2 ton conversion spindle w/disc brake mount for the 63-70 trucks this is great if u don't have a dually and don't need 8 lug wheels the kit comes with hubs I believe in 5 and 6 lug versions. This is basically a 1/2 ton spindle with the ball joint tapered stud holes enlarged to 3/4- 1 ton diameter ....so it is truly an easy swap...as u can use all of your original parts including the ball joints.

Apparently there is not enough demand for a 63-70 3/4 1 ton disc brake spindle direct bolt on if there was it would be on my dually!!!!

If you happen to have a donor truck (73-87) everything will bolt right up including the cross member if you drill two additional holes....i had all these parts but since im going to drop spindle's anyway; the amount of labor to remove and replace all those parts and purchasing all new wear parts just wasn't worth the trouble.....ok im going to shut up now before i start to confuse myself...............where did i leave my beer???.....Rushnbobo......

I was clear as mud.... What I meant was instead of using tie-rod adapters, swap the entire post-73 C20/30 steering assembly. Post 73 were all disc set-ups; parts are easier to find & typically cheaper.
