1963 Valiant differential rebuild kit and ring and pinion gears

I have just about everything in NOS for that rear end....at least according to my inventory ledger. I'd have to put my hands on the actual part to verify. I show a 2.93 ring and pinion, the carrier bearings, the pinion bearings, side gears and spiders (for non-sure grip) axle bearings and seals, and pinions shaft seal. In looking up some of the numbers, I find some of them are different from the '63 parts book to the '66 parts book. Maybe the part interchanges but the number was superseded for some reason? Bearings and seals are all the same, but, the side gears are 2070023 in the '63 book, and 2404194 in the '66 book. Same with the spiders.....2070025 and 2404195 respectively. The ring and pinions show 2070596 in '63 and 2743204 in '66. I'd have to dig it out to see exactly what's on the box or gears as far as numbers. The parts I have are genuine Mopar NOS parts, or, NOS U.S. made Timken when it comes to the bearings.
