There is a safety issue with reusing the stock arms...after 40 years on the car,who knows the stresses they have endured.On the CPP tech site,they were just going to re-bush the arms on the PHR Chevelle,but noticed small cracks in them.Most people probably wouldn't clean the arms well enough to inspect for that.
I am lucky I have the paperwork from my GTO since it was delivered...it was involved in something that made them replace one upper control arm,and dented the oil pan pretty good.That's why I started looking at upgrading the suspension...That,and it floats like an old Caddy on the Interstate!
