I got a phone call from a gentleman with a 300G that has a cracked right side exhaust manifold. Knowing how hard it is to find a replacement, can anyone suggest a facility that knows how to repair manifolds? I realize it is a very specialized job that is outside of the abilities of most welders, but may be possible. Has anybody found someone that knows how to do the job so it holds up over time? If it is even possible? I'd like to help him out if I can, and if you happen to have a replacement manifold you'd like to part with, let me know.
