          | I took the pulley from a 78 GMC 427 truck engine alternator - 2 groove pulley - narrow belt - chucked in lathe and opened up to accept the B belt - bore of pulley fits any 10SI alternator and with small size and deep belt - it charges well. Cast iron pulley so easy to cut deeper and wider .
