ok, heads swimming, 67 C20 Pickup

[Khyron]

Ok, ive been reading for a week or 2, and I think I got the idea, need someone to double check me.

I have a 67 C20 with leafs in the back, planning on a static drop, nothing crazy, just want a nice stance, However I wish to put Disk brakes on the front. I went to a local yard and got a fully assembles setup off a 74 C20 <i want to keep the 8 lugs cause thats cool. So, it came with spindles, rotors, calipers, basically they cut the control arms off and gave me the parts... now if i read right...

this is what i need to check

replace upper and lower control arms with 74 upper and lower ball joints.
outer control arms
steering linkage

and of course, replace brake lines with hoses and such


now.. what am i forgetting, are the 74 c10 and c20 ball joints the same? or does it need to be c20 ball joints?

will the 67 lower control arm work? I remember reading that it may interfere and I need a 67 c10 lower control arm and put the 74 lower ball joint in it.

I am a recovering Mopar guy, Im not sure of the interchange on the c10 vrs c20, I would like to eventually put lowering spindles on her, but I want to just get the disk brakes on first and maybe run it with lowering springs for now.

Please spell this out for me :-)

and yes, she will get new bearings, rotors and calipers, i basically just wanted the spindles.

nothing?

I'd respond but c20 isn't me. Hang in there someone will chime in. Use the search box above and check the box for 67-72. I know i've read the info for your question but right now i don't have a lot of spare time.

you wont be able to mount the 73 c20 spindles to the 67 lower ball joint. but the 73 and up lower bj should press into the 67 lower control arm. i do have a good set of c20 lower control arms from a 68 if you need them
c10 ball joints will not work. 2 different widths

[Khyron]

Thank you for the respinces :-) i did find this...

So the lower control arm needs to be replaced then? or should I just get another set so i don't destroy the ones I have?

On C10's, you just pop the old BJ's out & swap in lower BJ's from a later truck that would have had disc brakes. I would imagine the C20's are similar but have never done one to know for sure. Worst case, you might need the later model disc brake trucks lower arms.

[michael bustamante]

no need to swap out lca`s just the ball joints.

[Khyron]

cool, good to know, hunting for some drop spindles online, damn c20 spindles are almost twice as much at c10 LOL. if only I could put a c10 front on and keep the 8 lug rotors, i really like the 8 lug look.

Has anyone used these guys?

They definitely don't have good feedback. Google AIM, Airbagit.com, or ChassisTech. They're all the same company just use a different name as the years went on

They have customer service issues once they have your money, & many of their parts are of questionable quality. That being said, people still use them so buyer beware.

will 1974 c20 upper and lower control arms work on my 1967 truck? I may have an offer for a new set of loaded control arms for a good price, just not sure if they will work on my older truck.

[michael bustamante]

They will. As long as the 67 is c20.

Were the upper a-arm shaft studs 9/16" on C20 drum brake equipped trucks? Seems like I remember them being 1/2" on drum trucks.
