I have found the heater fan motor that will work and clear the O2 sensor and down pipe. By trimming the 5/16" shaft and cutting to length this motor I found at Oreillys and its new with warranty for around $35.
it didnt take much to make it work I just , it bolts right in the mount plate,
, it puts out alot of air and worked out great with the resistor, I just cut the old wire connections off and spliced then to th new fan wires mounted it and it clered inside and out
