I have a question for the experienced guys that have gone through this a couple of times. I am gonna resto-mod my 68 FB. I am curious as to how far does one go with a mock up before paint. Fitment of tires, body panels, suspension, maybe wires harness, fuel lines, etc. I would love to be able to go all the way with it before paint so drilling on the new painted surface is at a minimum. Also, I wanna be able to delete any un-used holes in the engine bay. What do you guys think ? Also, how far does one go with the planning before the first wrench is turned. I have an idea in my head how far I am gonna take the planning process, but would love get some opinions ? Thnaks.
