Smkymntn put a 3 gauge panel in his radio slot, it looks clean and is functional.
I like it so much that I'm going to do the same thing. I found the plate here Universal Triple Gauge Single Din Radio Face Pod I just moved my CB to the pocket location, removed the radio and put an MP3 amp below the console. Should be nice if I get out there and finish it up.
EDIT: So Adam was faster than me in replying, but I had a hard time finding the stuff, so I'm gonna leave the repost! ************
Thats a very sharp idea. Since My 60 has a SBC, I like your position better than the current aftermarket gauge location. I'm thinking putting fuel pressure too as my Mallory Fuel pump just got replaced and it was such a pain in the you know what to diagnose. I would like to monitor the pressure coming off of it so I can tell how its behaving.
