Any help would Be appreciated gonna have to run the 73 front bumper for now and loan him my wifes torque thrusts but Im Pretty sure we will make the deadline. Need my hours in a day.
I believe the Mustang rear will be a little too wide, but you can compensate for that with the backspacing of the wheels. I have an early Mustang 9" on mine. Sticks out just a little but it's a race only car.
I'll measure it tomarrow it's just got a locker and 411 gears with disc brakes and be easier to swap out then build anothet
If you click on my images you might be able to see how much it is. Not a lot but there is room for some more backspacing.
