Old CR exh manifold?
 

Tossing the idea around to build a manifold but I need an old one to build a jig. Anyone have an old one laying around? Cracked ones work too. If you wish I can build the jig then give it back to you. I just cant take mine off because I dont want to have the truck down for the day. I'll come get it and return it if needed. Can anyone help me out?
