I am in need of new upper control arms both left and right for my 1980 Valiant Regal CM, After looking online and finding stock standard reconditioned control arms on Hemi Performance.com.au at $154 a piece.
I wanted to see what it would cost me to get a set of adjustable control arms from the states as i do alot of travel back and forth i can easily bring a set back.
I am looking at a set of Adjustable upper control arms on Ebay for a 1970-74 E Body at $210 USD a piece.
