I talked with a fella the other day from a place called Champion Radiator out of Southern Ca.  He sells an all aluminum tig welded rad for stock apps in the $200.00 range with a guarantee for life . He was going to look into making one for this app.  I don't mind spending the money for it to be right nothing worse than a breakdown on the trail Cu's you short changed your mod. But, Like most of us I'm on a budget so I gotta take my time and save.
