Faze volt gauge - NEW on ebay $26 shipped
Faze air/fuel gauge - NEW on ebay $26 shipped
Halo reverse gauges - New on ebay around $35 shipped
Double pillar pod - New on ebay $15 shipped
Autometer pro shift lite with 6k rpm pill - Free from a buddy

All installation was done by me. I also did a write-up if anyone is interested.
