This bracket is designed to be used with the metric G.M. remote reservoir type 2 pump. Designed for street rod applications, it sits high enough to clear most chassis parts and steering gears. WILL NOT WORK WITH LOW PROFILE BRACKETS Due to alternator belt clearance (See Part# 411L). Pump is driven off the outer groove of a 3 groove crank pulley. Pump uses an aluminum V-belt pulley available from us or other street rod suppliers.
