I just discovered a hairline crack in the cam cover of my 1973 GTV. I was surfing for used covers and found this old post of yours. I'm sure the covers you were selling are long gone but I was curious how the hairline crack you noted in your post was repaired. Welded? Epoxy? Maybe I can repair mine. I know an excellent welder, actually he's a fabricator and artist when it comes to welding. I'd appreciate your feedback. Thanks.
