That is because the '63-'66 C20 and C30's have a flat lower control arm shaft, that attaches to the crossmember with regular bolts. Consequently the crossmember does not have the saddles necessary to accomodate the later model lower control arm shafts which are round. Converting a C20 or 30 to front disc brakes isn't as easy as on a C10. Here is a pic of a '63-'66 C20 lower control arm. There is the possibility that the disc brake lower ball joint will fit the '63-'66 LCA, but I have not been able to verify that.

the front to disc yes if you are going as far as it looks like you are i would take a little more time and update as much as you can and you will still have this truck when you are 50

[jrick63]

Has anyone had problems keeping the drum brakes?

[jrick63]

Take a look at this link http://minneapolis.craigslist.org/ws...257715560.html

[jtrichard]

good point Captain i think you use the original lowers and change the ball joints i could be wrong

[jtrichard]

yes they don't stop for crap the newer trucks went to discs for a reason

[jrick63]

Check the link out i posted. Do you believe that's the stuff i need?

[jtrichard]

4x4ing yours is so much work most of what we have talked about is bolt on stuff 4x4ing yours would be a lot of fab work... it would be nice but you might be 30 before you can drive it

[Captainfab]

Back when these trucks were new it wasn't as big of an issue since most everyone had drum brakes. Now days you have the cars and trucks in front of you, which have disc/drums or disc/discs slamming on their brakes and stopping in a shorter distance than a drum/drum vehicle can.

[jtrichard]

you need 2 wheel drive donner

[jrick63]

That's what i was wondering, cant take rear end, brakes from 4x4?

[jtrichard]

rear end yes front brakes no

[Captainfab]

I agree......changing to a 4x4 is a big job. The change to front disc brakes and power steering can be done in 2 or 3 weekends.

Just so I'm getting this straight, i can keep my engine ,Trans and swap rear end out. And it will drive smoother? Also recommend disc all around or just the front to start with?

[jtrichard]

front to start.... rear is nice but not necessary yes your engine and trans ... wont drive smother just less rpm at the same speed and parts (brake drums, bearings and gears that are much more available)

[jtrichard]

by the way where is maplewood?

[jrick63]

Just outside st Paul, mn

[jrick63]

about converting the fronts to disc. Will parts from a 80s c20 work? Spindles? Do i have to change control arms?

[jtrichard]

up to 88 i belive

[jrick63]

Will i need the control arms from that? Or will the spindles bolt to the old ones?

[jtrichard]

should just change the whole cross member

[jtrichard]

the lower arms wont fit your xmember i think if you get the right ball joints you can just change the spindles and ball joints and the outer drag link ends..... i would change the whole thing including the power steering

[jrick63]

So basically if i found a whole crossmember assm that would be the way to go!

[jtrichard]

Yes

[jrick63]

Ok thanks, just gotta start keeping my eye open!
