I will do full write up with pics soon, but here are some teaser pics of what I am doing. Full credit to Gringo for giving me the idea.
Pics are a little blurry. Basically, you remove sunpro gauge face, mod factory face, drill new holes, and mount to sunprog gauge internals and cup.
I will provide more pics/details soon, including my rear/factory style mounted sunpro tach. btw, that is the stock temp gauge. I added sunpro tach, volts, and elect. oil psi (try to finish up oil psi tomorrow)
