I love to keep running tabs of my "cost" on a project. I offset for sales/trade of parts etc. right now I am building a 66 dart that will have only cost me maybe 2 thousand or so by time I am done. got the 66 for free, paid 450 for 74 dart, sold 400 worth of parts scrapped the rest and kept the lbp disks and 8.25 rear plus rebuilt auto trans......pretty much the only new parts I will have to buy are the sway bars and radiator ( and some odds and ends).

I actually enjoy cleaning /rebuilding /detailing old parts rather than buy new, but some time you have to bite the bullet ad go new.
