2nd chance to make changes, what you you change?

If at ALL possible, you need to keep the car driveable to keep your spirits up. Just going for a spin and hearing the exhaust will re-motivate you to finish the car. Who cares if it is in primer or 4 different colors? Go for a spin! Get your thumbs up from random people and then go home and get back to work. I am blessed to have a finished car I can cruise/race so I am in no rush on the Duster making noise. But if I DIDN'T have that, I would be stressed out for sure and rushing this build.
