What is your trick to installing hardware without leaving tool marks? This is one of the biggest mysteries to me on how meticulous restorations are done. I can't touch a piece of hardware without leaving marks, similar to how I can't spend two minutes in my garage without getting some kind of dirt/grease on me. For instance, your driveshaft bolts. I'm assuming they are properly torqued? I'm looking, trying to find witness marks on your hardware, and I can't find them! (thats a compliment)
