We are having a difficult time fitting the radiator and the fan into the restoration. The truck is a 1951 3100 with engine #FBA13701 that I believe is a 216. We are using the X radiator support. Sourced a correct radiator but there so little room for the radiator fan. Someone suggested using a "short shaft water pump"? Any suggestions would be appreciated. We are excited to ge this dog on the road! Best Haasman
