Hello I am redoing a 1948 Plymouth special deluxe. I bought the fat man steering kit and olddaddy disc brake kit. I took everything off the car last night and found my control arms bushing extremely worn. (both upper and lower) I saw you guys were talking about MOOG cast steel 1941-56 style upper arms. I could not find them anywhere to buy. Do you guys have the part numbers? Should I use them? Or try rebuilding the old ones? Also if I rebuild the old ones do I need the special tool the book calls out to use?
