54 3100 w/235. Last night I was installing a new interior firewall cover. becuase it's so difficult to see up under the dash a corner of it got caught on the wire going to the amp guage and pulled the terminal lug right out of the back of the guage. do you think there is anyway to put it back in or am I looking at $50 for a new guage? I haven't pulled the guage cluster back out of the dash yet.
