Rear differential fluid

Howdy-

I have a 1994 Class C RV built on a E350 DRW chassis and 7.5L 460. The door code for rear differential is 62. All I can find on that code is Dana 8100# open. Would a fully synthetic 75W90 be good for this? or do I need a heavier weight?

Thanks in advance,

Thank you! For some reason the only weights I see on Amsoil are 80W90/75W90 or 75W110. Not hung up on Amsoil but have had good results with the engine oil
