Blower motor resistor

[gprimm]

My son's 1978 wagon, 305 small block and A/C needs a new resistor. I went to the dealer and they said there was only one listed so I purchased it for $32. Turnsout the one purchased has 3-prongs and the original has 4-prongs.

Has anyone run into this before and if so, what was the resolution to this problem?

Thanks,

Went to NAPA, they said "Dealer item". Did you get one from there? George
