Hello,

I got a 2wd with a 531W and I need a fan shroud. Will any shroud fit?

 

You'll probably need to figure out which radiator you have and get the shroud that goes with it or upgrade to electric fans.
The 351W was never offered in the 73-79 F series from the factory.

 

I'm still looking for a fan shroud for my 351m. I have an updated radiator, and I have a feeling I'm gonna have to end up making one, without dishing up $100 from a catalog...

 

One for a 302 may work,kinda depends on your radiator. You may not need one unless you want it for safety from the fan blade. I'm running a 460 in my 79 F-100 with a 302 radiator because the big heavy duty 460 radiator went bad. I have no shroud and the fan is about 3 inches back from the core. No heating problems in last summers 95 degree days. Not going to change it ,if I keep it I,m going to drop in a 302, I'm tired of feeding this hungry beast.

 

Any 302 or 351M/400 fan shroud (for your rad size) will fit. I've used the same shroud with all 3 in my truck.

And welcome back, I don't think I've seen you on here in a LOOONNNNNGGGGGGG time.
