Can't get Pro Parts headers to fit.

Engine position results:

Measured where my engine position is and it matches the numbers on the reference table perfectly. Engine is sitting where it should be.

Dumb ProParts headers still don’t fit. Feel like I’ve wasted so much time and money and beginning to think I just don’t have the skill for this engine swap.

Guess I’ll just keep on cutting until there’s nothing left of the fenderwells. Don’t care anymore. Stupid cars. So frustrated. Been working for so many months on this thing. Thought buying good headers would help. Absolutely no progress at all (as usual).
