Time to put the vinyl on this side.
I have a decent amount of experience with vinyl but it doesn't matter how many times I do it, I still get nervous, especially with art this old.
Basic positioning and rough trimming to leave about an inch of bleed around the perimeter of the cab
I always hinge my large vinyl pieces, sticking down one half at a time with a very light spritz on both surfaces of water and dish washing liquid mixture (single drop to 32oz of water).
Top half stuck in place, now just do the same to the bottom half
And it's all down, I roller it pretty hard with a laminate roller to push out the small film of water and any air bubbles
