I use Morgan Automotive Detail. http://www.madmodeling.com/
I haven't seen anything with that kind of detail though. Even for his you have to add the vacuum canister.
Excellent tutorial Matt! I'm building that kit for the Cannonball Run and I'll use the body mods. I'm using modern size wheels and dropping mine down so I'm replacing the entire chassis. I had come up with a similar remedy for the rear axle but had clearance issues with the tires. Thanks loads!
Nice work!
Dunno if its too late, but I used rare earth magnets on one of my builds to keep the one piece front end in place. I glued two to the front end and two to the body. It allows you to keep the front end aligned.
