Thanks, guys.
I am still waiting to get the Fox back to the shop--waiting for the roof and lighting at the shop to be fixed, that is.
The good news is that I have saved what should be enough money to pay for everything the car should need to complete the project.
The only remaining "big" item to buy is a Griffin (unless somebody else has a recommendation for another brand) radiator, which I am budgeting $800 for.
I also still have to order the driveshaft, but that will wait until the transmission and rear end are installed so I can take a 100% valid measurement. A one piece shaft shouldn't be a problem when that one piece is only 35" flange to flange.

That's about $300.
Other than that stuff, it's hoses, lines, spray paint, powdercoating for trims, etc.
