Mike. I posted Chick's link because those were his findings. I have always left the dogbones natural. It's obvious the nuts and shims were not painted due to the assembly process. I did not immediately notice the nuts appeared black in the photo.
For some strange reason I didn't see any pictures in the links. After rebooting my PC do I now see what you are talking about.
So the control arm, dogbone and mounted bushing's was painted as a whole unit. I can accept that. Were the end washers and bolts painted black too? My thinking is the washers and bolts were added during assembly and torqued down once the full weight was on the chassis (motor, options, etc...). Or were they installed lose on the dogbone ends and painted along with the rest?
Reviewing old posts
Plan on dropping the subframe in a few weeks for a nice winter project.....so what's the verdict on the end washers ? Pg # 36 in Chick's build the "unit" is gloss black. Ball joints natural. Final assembly fasteners painted ? Shims natural? I hate replacing them because the car is still tight ,but the bushings show some dry rot ,so they are getting bagged and shelved.
