I'm doing a brake swap on my 68 and just removed the spindles to clean and paint them. I have replaced the upper control and ball joint in the recent past, but not the lower control , there is nothing wrong with them as I can see or hear. Should I replace them or just clean them up. The control arms are the original ones.If I replace them what kind? oreillys, auto zone have them ranging from 25$ a piece to 75$. This car is a cruiser, please any info will help.
