The tag on the rear end showed 2.4? , not my choice of gear set but the rear end is in great shape and all there for $75.00 , I for got the gear but it was a tall gear :glasses7:
It will be fine in the 66 Valiant with a 360. You will have plenty of power to get that light body up and down the road. The highway gear will be nice for economy and top end....
I peferred the 2.76 in my old Barracuda over the 3.23 that I eventually swapped in...
