1963 C-20 Disc Brake Conversion

[decodan]

Hey Guys,
I know this has probably been covered but I did not see it.
What do I need to be looking for to change the front 8-lug drums to 8-lug discs on my 1963 C-20. I picked up the power master setup from a 1/2 ton truck and figured it would work for me. If that is not right please let me know that too before I do the change.

I figured I would would do it in steps. So I wanted to get the safety of the newer power master setup and then later when I have accumulated the parts do the front discs.

I do not want to change to 5 or 6 lug setup. If finding a 3/4 ton late model for a donor is all I have to do then fine but if the later a-arms and spindles are not going bolt up I need to know.

Thanks, Dan

The only conversion kit I've found is from Jim Carter's. The part number is HP524.

Haven't done it using the 3/4 ton later models as a donor, but if the 1/2 ton is any indication - then use parts from a 71-72 if you can, but the 73 and later should work. The A-arms look the same, but I'd get new ball joints and see if they will press in. On the 1/2 ton if you use the same a-arms but use ball joints and spindles from the 73 - up, the camber will be slightly off. The camber problem can't be adjusted out, but I haven't had and trouble with tire wear. Don't use the drag link from a 73 and later truck, it is made for the wider frame and will cause problems.

Get a front end rebuild kit from one of the suspension suppliers - Just Suspension, Performance Suspension Technology (I used them), or Performance Suspension Components.
