This might not be an issue but I would have a hard time believing what's inside a bearing box if the original part number has been crossed out. Just sayin'

I just found this on ebay. this I can buy. same Michigan part # 1092T buy look at the parts it says are inside. 1-7377 and 3-7376. That is different from the other box. same seller, same brand
