I agree on the Napa chassis. Mine are still doing great after 5-6 years when I rebuilt my frontend. When I got them they had a dana logo or spicer and "made in usa with global materials". So whoever reboxes spicer/ dana will be the napa peices. I think I remeber hearing raybestos and AC Delco re-boxes them but I can't say for certain. I did use a AC Delco pitman arm on mine and it looked the same as the Napa one I returned. I've read lots of good reviews on pro forged as well
