71 Duster 360 (new project)

all bolts tightened...brakes on....brake line on ...brakes need to be bleed......taking slicks off new rims and putting them on old rims...one of the tubes went flat...i think it was the valve core...the racing tubes have that screw in valve stem...saw it bubbling...and replaced it....going to see if the tube holds air over night ,,,,if so everything done tomorrow.
