Also the plate has been O-ringed on the blower side and includes a set of flathead bolts to mount to the manifold and O-ring.
RBS can supply the customer with blower studs if needed. The plate has been anodized to help prevent galling and the plate has been machined to lighten it up to keep the weight down on your hot rod.
To measure if this set back plate will work for your application the racer will need to measure from the center of the left most forward bolt hole on the blower snout side of the supercharger case to the end of the case. The measurement on the blower case should be 1.625" to use this set back plate. If the measurement is 2.625" this plate will not work on 1" to the front blower cases.
