Welcome to the dark side. Alignment is always an issue. It might save you some headache to line the cab up with the hood where its gonna be on the frame. The gap between the cab can be fixed this way. Just dont mount the cab permanent till the gaps look right visually. This is a common thing on all these trucks with hoods.
It is doug. So mine is flyin together. My only complaints are, no visor and no tilt hood. Otherwise great kit, little to no flash, not too much chrome.
Im lookin for this lettering. I dont know exact measurements, im guessin theyre approx. 20 to 25 ft long, around 4 1/2' tall tapering yo 3 1/2'. The small letteringis around 2 1/2' and around 15 ft long
