This is a nice very clean used 6-71 blower front cover which will fit the popular 4-71, 6-71 and 8-71 blowers with the smooth outer bearing plates. Will not work with the bearing plates that have the scalloped outer side. This cover comes with a nice finned tri plate, cover gasket, snout gasket, tri plate gasket, allen bolts and a check valve. The hole in the front cover needs to be tapped larger for the check valve.
