It sounds like he has one of those spacers to isolate the heat from the manifolds that Code3 or TVT sold way back in the beginning. Get a longer bolt is the answer. Measure what you have and add a 1/4 inch and go shopping. Needswings sells longer than stock bolts for their manifolds. Rob may have exactly what you need if you can't find it at the local "Casa de Tornillos".
