I ordered my 4 pack gauges & PDIM from
http://chevypartsplus.com
Cary was great to work with.
the prices seems to vary, depending on vendor, but From ChevyPartsPlus Website
the 4 pack gauges are $372.00 and the PDIM is $151.20. + S&H.
I have seen some prices higher, and some lower.
I hope that helps,
Tim
