[/ATTACH] This is for a Ford Flathead 1937-1948. This is a rare passenger side with cast bung for water heater fitting. Sold with an cast dual sheeve pulley to replace the stamped steel one! - See picture of my 35 Three Window with a similar pump installed - see dual sheeve for the ScOT blower and hot water fitting and hoses for the 39/40 heater! Must be drilled and tapped. For my blown 35 Coupe with 1948 Flathead - I sent a similar pump to Skip Haney for a rebuild with his high flo impeller and new ceramic seal & bearing - he can drill and tap the bung as well for the heater hose fitting. $70 + shipping
