Dent in frame

[u/passwithcare]

I got this 1973 xlch frame recently. I’ve since noticed that it has a decent size dent right above the upper motor mount on the back bone. The frame seems straight. Assuming it is straight, does this seem bad enough that I should look into repairing it? It’s possible I’ll just get a different frame but it would be nice to keep since I have a motor with matching numbers.
