help with my crank

[TD]

Here are some pic's of the only bad spot I found in my lower end. The crank shaft is mint here. There is a small devit and a scruffy spot slightly discolored. If you scrape it with your fingernail it is slightly course, not bad. The divit is small but easily felt. The motor was rebuild, run for a few months and put up for 40+ years till now. All else is nice. Should I open the can of worms and go after this piece or put the bad boy together knowing it will have good oil to lube with?
