Pull the skid and drive shaft, empty and flush the exchangers and bring to any decent weld shop.
JB weld is a crappy fix and is not reliable (do you want to be as far as possible from home and have it start to leak?)
I welded the tear in the front exchanger on my old ZR, and it lasted another 7,000 miles.
You should be able to get it welded for less than $40-50.00.
The only time I would use JB or epoxy was if I was on a trip and had no other alternative to get some miles in.
