FWIW, I replaced my 110 gauge per instructions with a second hand 94/95 that was supposed to be good. Removed conditioner, everytime the truck would start to warm up the gauge would peg itself in the red. Being paranoid, I kept shutting it off, bought a new sender just in case the one in there wasn't correct, still the same. No sign of overheating and no indication from a laser thermometer either. That was the final straw and I decided to just do it right and replace them all with New VDO. I haven't finished putting the truck together, but I anticipate a lot less headache, more information and better visibility...I'd suggest going this route.
However, if anyone is still looking for a 94/95 gauge, I believe I have two plus a stock NAS110, all of which I won't be using. I'd like to keep the 110 just to give the new buyer all the original parts I can, but the 94/95s are up for grabs for any offer. No guarantee they work, but I find it hard to believe that two failed the same way...I think I had another wiring problem causing my issue.
