Cool.
Yes, I agree with you. I don't think the Confederate Navy Jack (I misspoke in my earlier post) will fit on top of the sleeper. Best to put it on the back. I think the "01" will be too big for the doors like you said.
So the 1/25 scale "General Lee" comes with the Flag on the decal sheet? I saw the model on the shelf at a LHS, but the Flag wasn't on the box art. Not "PC", I guess.
I think using BMF on the hood strip, door trim, & windshield trim would be a good idea. Are you going to put the Confederate Battle Flag on the roof & the "01" on the doors?
If I remember correctly when I built my L700, the doors were the only real pain. The mounting location of the battery box is a little vague, but not terribly problematic. For some reason, it tends to have a little bit of a "shovel nose" look to it.
Here is a link to a Classic Truck Auction that is happening in Friesland, Wisconsin, on July 25th. Looks like there are a lot of Diamond-T & International trucks,
