I am fixing up what I believe is a 1948 BFG Schwinn. The bottom bracket was caked with grease. I usually take everything apart, clean and put it back together, but when I finally got down to the metal cups, I discovered that one of them is all torn up. When I measured the inside shell of the bottom bracket, I got 2 1/16 inches. The replacement cups I see on line say that the inner diameter should be exactly 2 inches. Will those replacement cups work on my bike? By the way, I punched these old cups out without any issue at all. I've never replaced cups before. Is it as easy as it looks?
Here is the link for the replacement cups:
