[gmcdeadhead]

can the power disc brake conversion be done on a 1966 c-20? i always see it mentioned for a c-10. what parts would you need from what years to do this , thanks.

73-87 C20 parts will work.
You will need all the steering parts and everything from the a-arms out.
You will also have to swap M/C and prop valve to a disc/drum version.

Most folks miss this option, pickups can cross parts up to 1987 but one can also use the front crossmember etc from a suburbar all the way up to 1991. They kept the same design until 92 as the 87 pickups. Kieth

ps, I found a wrecked burb for $900.00, used the TBI350, 700r4, computer, power steering box, wiring harness and tilt wheel on my 66 GMC...

so if i find a junk 73-87 chevy truck take the whole front end off and all the linkages? i should be able to grab the power steering parts also and do the power steering conversion to . right?

Yes.
However,... You will need a set of p/s adapter plates to adapt a p/s box to your frame.
Member captanfab on here sells them.

Yes, the C20 disc brake conversion is basically the same as for a C10. The one exception is that with the '63-'66 C20's you can not change the lower control arms. This is due to the '63-'66 C20's used a flat lower control arm shaft, versus '67 and up use a round shaft. Hence there are no saddles on the crossmember to accept the round LCA shafts.

Thanks for the recommend Keith
