Since discovering that my printed circuit board has separated and some of the copper has corroded/flaked away, I'm curious if the board for the other round gauge clusters (w/o tach, etc.) will work. I've come across 4 or 5 Montes in just one local yard alone (it's Flint... old decrepit G-bodies run rampant here). I may try to find a good one out of one of those, but I'm also trying to find sources that sell them new. Only place I've found so far that sells them & guarantees they'll work is eBay stores, and they want over twice as much for the used pieces as I've paid for everything to do the swap this far. Someone please chime in here
