Thank u “Mike” and “Chevy til I d” I have a 1957 Chevy 5700…checked NAPA they were a no go and rockauto doesn’t show anything for a 7/8” bore…I did see another thread where a “bolter” used a C60 application that had the 7/8” bore just has the inlet on an angle as opposed to straight like my setup…guna give that a try if no good I’ll contact White Post like Mike mentioned!!!!
Thank u men
Mike
