Wow, that is a nice mill you're building here! If you need I have an electric vacuum pump I removed from my Excursion I'll donate to your build as I don't need it because my engines have vacuum pumps on them. Give me your addy and I'll send it and the wiring connector from the truck. What color do you plan on going with? I love this body style. I just got another cummins truck to build for a fellow in New Mexico. It's going to be a 72 Longhorn 4x4 with a bale bed and a cummins. I look forward to your progress!
