Finding Front Control Arm Bushings

[GASoline71]

I did a search here and didn't find what I was looking for. I build engines. I know squat about suspension stuff. I'm looking for front, upper and lower control arm bushings for my 1972 GMC C1500. Stock replacement rubber bushings are okay by me. I've seen new shafts, but it appears that the new shafts come with nuts and seals but the bushings are not included.

Unless, I'm AFU here... am I looking in the wrong stuff? Am I overlooking something super simple? I have exhausted my internet searches and will start making phone calls to real people thumbing through a real catalog very soon.

These bushings have to be available somewhere... I mean, these ARE the most popular trucks The General ever built.

Who stocks the bushings?
