Another source is the late Crown Victoria/ Mercury shrouds at the local salvage yards. The replacement electric motors can be obtained from NAPA. Cutting the shrouds to fit is no big deal. I have the 2 speed style adapted to my 67 FORD XL in the original 67 shroud.
Also if you happen to see a X Crown Vic police car 95-97, they had a 1 speed electric fan inside the shroud that also had the engine driven fan.
