Latest project is to change my stock gauge cluster over to Auto Meter Pro Comp. I used to have these gauges in my old 1979 blazer, but when I got my new truck I took them all out because I wanted to do this swap at some point.
I think I have a reasonably good start. Still need to do convert all the wiring, but I'm off too a good start. I will want to mount one more 2-5/8" gauge in the hole where the stock tach would have gone. My other gauge not shown here is a mechanical oil pressure gauge. My method for making cutouts in the back panel that holds all the gauges evolved as I went, but I am pretty satisfied with the results.
