Was doing some web page jumping the other day and came across the R&D wedge and VTS rod kit (part number is either 15-1893 or 14395003 hard to tell on the site) for $164. On he GH site both Riva items together go for about $200amd $206 for the R&D kit. Does anyone know if that is the right part number? Im a big support of this site, but cheaper is cheaper, if it was on;y 10-20 dollars I wouldnt bother, but this is a slightly larger gap.

Also why is the Riva one 2 degrees and the R&D one 2.5? I tried R&D's web site but it kind of sucks.
