OH BOY!! I have a problem!!!
Not sure about a cast iron pump with the outlet on the pass. side. But I do have 68 340 GTS core radiator that has good top and bottom tanks.
eBay auction number 110373322594
I bought this radiator off eBay because it is shows to be a number correct for my 1968 Barracuda. The problem is when I pulled mine out of storage the bottom outlets are on different sides. 1967, 1968, and 1969 Mopar A Body water pump outlets with the 318 and the 340 are on the drivers side. 1970 shows the water pump outlet is on the passenger side.
I think the bottom tank has been switched to accomidate the 1970 up water pumps when it was recored. BOY OH BOY have I gotten myself in to a mess!! Is there another water pump that I am not aware of used in 1967 thru 1969?
