There is always a part in a long car project that makes you wonder why you do it. And it looks easier to quit. When I was building the SuperBirdo car we spent a month of Saturdays and Sundays modifying the wiring from 1995 to 1996 with limited donor cars. That was a rough month.
So many people give up. Any of us who have been around here for 10-20 years have seen everyone who started a project with big ideas only to sell off all their parts and the car wholesale on the for sale threads.
Keep going! It looks great!
