When pressing in the upper and lower control arm bushings, are there any critical dimensions required. How do I know that the bushing is located correctly in the control arm. To far or not far enough. Does anyone have a drawing or diagram that shows the correct location. Is there a GM drawing? I need this information for the machine shop doing the pressing. Please help.

Haven't seen a drawing denoting the dimension, but, this is what I would do.

Remove the arm, measure from the inside edge to inside edge of the bushing hole. Have a piece of piping made to this length. Remove the OE bushings. Lightly sand the arm bores with some crocus cloth, clean, and lube the bore and the new bushing casing. Place pipe between the arm bores and press in the new bushings. The bushing flanges are seated against the arm. Lube the inside bore of new bushing and the cavity the bushing fits into on the frame, install arm on car, hand tighten bolts. Drop car onto ground, with tires & wheels, of course. Tighten all bolts.

I believe the bushings have a collar on them. Press them in all the way until they bottom out.
Any machine shop should know how to do them

Thanks for the replies. Before I had the original bushings pressed out I didnt take a picture or measure where the bushings sit in the arm. I was hoping that it would be obvious where the new bushings should sit. Thanks again.
