I was taking the cluster out today to clean a few things and put a new speedo cable in when I broke one of the pins on the circuit board that connects to the wire harness. Has anyone fixed this before? They seem to be aluminum so they aren't soldering for me. I was thinking maybe putting a tiny machine screw up in there to act like the pin and hope the connection is good enough. I don't know how else to do it because these pins are pressed in there and it just snapped off.

Another thing, where can I find the little plastic bulb holders? One of the tabs broke off of one of them and I'd rather get another one if they are available instead of taping it down.

Lastly, what speedo cable should I get on my 71 Duster? I bought one from napa but when I went to put it in I noticed it was about 40" while mine was much smaller. They didn't have anything other than 20" and 40". Is there harm in putting a longer cable in like getting an inaccurate reading? I'm not really sure where to get the right cable at.
