Upper control arm I.D. or I think I got took

From what I have found out today. I called Firm Feel, and gave them the O.D. measurements of 11 1/2 inches, from outside of bushings, to out side of bushings, and I.D. measurements of 7 3/4 inches bushing to bushing, and he told me they were "B", and "E" body Upper arms. The factory arms are real close to the measurements without the bushings.
Measurements on the firm feel w/o the bushings is... O.D. to O. D. 10 3/4 inches. In side measurements are I.D. to I.D.
7 3/4 inches. factory arms are about the same.
