I had a 69ss with pro stars 4.5 back 5.5 out 10.0 overall with et streets 29x12.5. I had to do little and i mean little work to the front part of the frame. The tire would flex and rub alittle so i tapped in the frame. The tires filled up the wheel wells perfect. The car weighed 3810lbs went 10 teens on the front mickey thompson street tires with 3.5 rims.
Hope this helps good luck
