9 teeth on pinion and 41 on ring gear. 41 divided by 9 is 4.56 does sound right? If so I am over joyed, I have a ratted out 67 barracuda I may build with a 360 tunnel ram, the rear is 49.5” wide, I’ll do the 3” inboard conversion on the leaves. I also have 10x15 welds that I’ll put a 28” drag radial on. Might just work out good.
