This is an original vacuum fitting elbow that screws into a port on the rear of your cast iron intake manifold for a chevy engine. Should not be used with an aluminum intake because I believe those fittings were different from the factory. Anyone can correct me if I'm wrong on that. Probably used on multiple years but this particular one came off my '69. It is used in conjunction with a steel power brake tube attached to a hose that ran to the brake booster. The threads are in great shape. The overall condition is pretty good but I would suggest having it replated for show. *Asking $25 with shipping included to lower 48 states/Canada extra. Feel free to PM me with any questions.

I currently own a 1969 Camaro SS350. Although the original drivetrain is long gone, this 4/speed car has a March '69 HC coded block with #041 heads. The transmission is an M20 Muncie #660 case and the rearend is a BS coded 12 bolt posi. Built in Van Nuys.
