XRF Chassis parts sound like good quality parts, they use the same part number as Moog. Supposedly manufactured in Canada. Also ProForged seem to be very good quality. I just used some of these on my 67 Coronet, and was very impressed with the way they looked-a lot nicer than Moog parts. Quite a few years ago, I purchased a kit from PST. All of the parts were from China. The lower ball joints only lasted about 5000 miles. I hear their quality is better now, don't know-won't use them again.
