I'm in the process of installing a set of QA1 tubular lower control arms on my 70 Cuda and I would like to check in here if anyone here has any experience with these control arms?
I have a new set of Firm Feel greaseable pivot shafts with a nylon bushing, is there an advantage of using them over the OEM style pivot shafts that the QA1 lower control arms are delivered with?
Any thoughts are welcome
