    By the time you find one and the goodies to use it about 350 to 400, and its still a 5k tack. I pulled all of mu gauges and replaced them with VDO the tack and speedo are 4 ich the rest (temp,oil,volts,fuel and vac) are 2 1/8 the smaller fit in the 4 holes nicely found a place out of Seaatel that sould a nice kit for about 500. all the gauges are ele. the speedo can be recalabrated(?) in about 2 min!

    I understand the jeep thing I drive a BLAZER!!

    Also, be careful of the OEM tachs from '67 - '72, as they are notoriously inaccurate. My original tach in my '70 Blazer reads several hundred RPM high, and I have heard of many (most) others that do the same thing. One of these days, I am going to figure out how to recalibrate them.

    Golden State Pickups has a replacement tach that reads up to 7000, I think. It's not original, but fits in the same hole and looks like the real thing. The original factory tachs are a little iffy, There is a "pot" that youn can adjust from the rear to get it a little better. It's behind a little yellow, usually, round sticker. http://gspp.com

    It a F-boday tack from a 70 firebird or such had one for a bit. The real problem here is not can you find the tack you can for about 300 or so all said and done but its still the very flaky gauges, The amp gauge is is based on a 32 or 34 amp alternator. The temp reads C to H now just what does that mean! As well the oil read L to H. The VDO's arent much more and read real number that mean something pluss they look like there go there!
