Hank, 2 things 1) we have about 20-25 FGFs here in Houston...many are part of HALF ((housto0n Area Legendary Firebirds), some live in Houstron, some up in Woodlands, Tomball, Magnolia, Pattison (out west of you)...all around town...email me and I will put you in contact with the group... my email: bsefeldt@mhinc.com
2) when I had problems with my gauge, it was the printed circuit...and every time we fixed something there, something else stopped working...I ended up buying a new printed circuit and all was fine after that...this was about 13-14 yrs ago.... (sold car 2 yrs ago)
