I talked to the shop here in town "Custom Metals" and he said that he would be happy to assist in the repair of broken cast manifolds. He needs to have all the pieces that you have. and a head or gasket to measure holes off of if any of the flanges are broken off. I will provide The heads or gaskets to him for the repair process. Lynn also asked that you contact him directly to work out details of shipping & Repair costs. His e-mail address is custommet@xxxx
