I am looking to see if all of these numbers are for the same 35 tooth speedometer gear. The original number was 2538935. A Chrysler dealer told me it superceded to part # J3212735, that is NLA. Looking around on the net, I find a part # 52068157 for a orange 35 tooth gear. Are all these the same? Trying to match a gear to a 7.75x14 tire and a 3:54 axle.

Thanks
Dan
