Repairing 3" heat exchanger on M-50 diesel

I am just finishing up a complete rebuild of my M-50 Universal diesel and I took the trouble to sandblast the outer shell of the 3" heat exchanger. I noticed a very small crack near one of the fittings in the brazing joint. I was wondering if anyone has had experiencing in rebrazing any of the joints on a copper/brass heat exchanger. I am a medical gas plumber and have had some considerable experience in brazing copper tubing and fittings, but I'd rather not find out my limitations on this. Any help out there?

Solder will be safer here.
