I have a 1972 Formula with a bad wiper motor. The problem is I'm not sure what to order to replace it since I'm not sure if I have a type 1 or type 2 motor and none of the replacement ones I've seen on Ames Performance, Year One, Classic Industries, The Parts Place Inc., etc. seem to match what I have. The part number on the motor I have is 4939300. There are some other numbers on the motor as well - 8790844, 278 1 4 B. The pump has the following numbers 24007191, 022698. The pump is black plastic with 90 degree turn hose extensions. There are a total of 5 wires - 3 to the motor and 2 to the pump. Any suggestions as what to order?
