Control Arms

Most likely asked before. Are the 2wd upper and lower control arms the same for 67-72 1/2T & 3/4T ? I know the ball joints are different.

thanks, steve

Re: Control Arms

IIRC, the uppers are the same but the lowers are different due to the larger diameter hole for the lower balljoint.

Re: Control Arms

I think The 71-72 were different for use with disk brakes. The GM parts show the 3/4-1 ton use the same upper for 71-72 different # for earlier. Did not check on '73-up.
