Nice truck. I remember that truck from around here several years ago. Congrats on your jump into the deep end. You will have fun with that one. I gather a wiring harness is first on the list? Having just undertaken the very same project I can say that it's easiest to pull the gauge clusters and get them done now and put them back at the same time with the new wiring harness. Keep us all posted on your progress.
