Finally drivable after 9 years... help me decide what comes next

Dr. Diff on the axles. Put new tires and wheels on it, 9 years in getting it running is alot of time and money vs using old junk tires and wrecking the car.
Run factory 15 X 7 with 4.25" back space.
Aftermarket reproduction ones only have 4" back space.
This will allow you to put a 275/60/15 on the rear and a 215/65/15 on the front with no rub issues if your suspension is in good shape.
