When to say when with a project car....

Getting the parts you're owed? Take a truck and go over and get em. That's simple.
Right on the money small block.
Get the rest of your stuff first and go from there. If the guy's as laid back as you say, you have to go get the stuff, he'll never bring it to you.
Keep the car and fix it when time and finances allow.
Don't do anything you will regret later!
We all have, and that's me in spades!
drive it and enjoy it for now.
