Just have to retract a previous comment I made about these guys. Previously, I said that they were not helpful with installation questions I had about the $600.00 worth of stuff I bought from them (alt, dual battery relay, cables, etc. etc. etc.) Well, apparently I simply did not ask directly enough because I called again today and Steve spent a ton of time walking me through everything part by part according to my shipping list. So, now I think these two guys are extremely helpful (stan and steve) and would not hesitate to buy from them for my next truck project. Plus I conferenced them in with the people from March and they answered all of March's questions so I could be sure to have the right billet brackets!!
