I bought a set for my 67 dart a few years ago and i'm very happy with them.

It's been my experience over the years that their "Accessories" are cheap crap and best avoided. However, the hard parts for suspension, steering, engine, brakes, etc. are top shelf and are well worth the money, and they carry some really hard to find items. Hope this helps
