I have a 1981 Chevrolet C10 with a 350 that my dad dropped in last year.

First off, my speedometer does not work and none of my gauges light up when I pull the switch. Bad Fuses or problem in wiring?

Also, my truck has a lot of vibration and rattle as well as the fact my panels don't quite line up(fender with hood, doors with bed). Could that possibly be just bad bushings that go with the cab to the frame?

One last question, any good websites to find parts solely for these models of trucks(other then stylin concepts)?
