Just received my $325.00 3.55:1 R&P from Mothertrucker, fast shipping and everything appears to be excellent quality. (not realy sure how to tell other than parts are clean, undamaged, and seem to mesh together just holding them??)
I also got an instruction manual which is several photo copied pages, but seems thorough.
I asked about an installation kit, and he says he does not intend to offer one, but is working on a parts list that uses Napa parts.
