I'm rebuilding and converting my factory air in my 69 F100 to 134a and I知 looking for recommendations on what size fan w/ clutch to use and I知 also wanting a shroud. Back 20 plus years I took a factory a/c unit off a 72 f100 with a 390 or 360 engine truck that was going to the junk yard. I took everything but the compressor mount which I had to buy one for a 6cyl. and put it on my truck and it worked pretty good best I can remember. I also got the radiator and had to modify my radiator support for it to fit with the factory a/c condenser. The radiator measures 28 across and 20 top to button.
Thanks

 

I thought Dennis Carpenter sold 300 fan shrouds. But I don't see one on their on-line catalog. I think it hard to find a good used one. If you have a local Pick-N-Pull JY, you might go there and find an electric fan and shroud assembly off some vehicle you can fab up some brackets to mount.

 

OP needs to go to Carpenter's website and look at the specs of these two shrouds. Either one should work, but I'd be more inclined to go with the 360/390 version.

D3TZ-8146-B .. 302 Fan Shroud & D3TZ-8146-C (replaced C8TZ-8146-K) .. 360/390 Fan Shroud.

The D3TZ-C shroud also fits 1965/66 F100 2WD & 1966 F100 4WD like it was made for these trucks, no mods required.

I'd stay far away from those electric fan motors, as they were crap from day one!
