Prototype update: Gotta find some glass that's the right size, just have some plastic in the face plate for now but here's my tentative entry. Uses the guts of either an FJ60 or FJ62 tach, direct drop into the housing, no cutting or gluing required. The original 2 mounting screws are used to hold it in. Uses the original wiring harness as well, and there's a place to click the original illumination light in too.
I think I may have a couple little final tweaks to get this exactly were I want it, should have the little mounting bracket bent and ready to mount today. Once the design is checked for in-vehicle fitment, I'll see what I can do about getting some quotes on CNC machining the front plate out of aluminum, but for right now, the intention is to make a silicon mold and cast it in high impact resin, then have it sprayed at my buddies autobody and paint shop.
(This will be mounted between the emergency brake handle and the heater underneath the dash, road testing to follow soon after.)
