c20 control arms

[jeremys14]

will c30 control arms work on a c20?

 

[Bagged Dually]

I highly doubt you really still need this info if it's even correct, but I've heard that all half to 1 ton control arms are the same on 2wd trucks. If I'm wrong someone please correct me and I'll learn something also.

Yep, C10 is different. C20 and 30 are the same to the best of my knowledge, and it appears by Retro's data reference the 20 and 30 are the same.

I think the biggest difference is how they mount. C10's have normal rubber bushings, while C20 and C30 have these big hex nut pivot things.
