I'm curious if the water pump/fan shroud are different in 2wd vs 4wd? I'm using aluminum tank with SPAL dual electric fans. No issue with 2 inches less clearance.

I'm doing the same mod as you, so I'll be following your progress closely. Let me know how I can help with measurements/photos etc.
I don't really know that for sure, but I've read about it a few times on this forum. I'm not sure what the reasoning is, but if I had to guess I would bet it is to provide more clearance for the front axle. Just a thought. If I do end up moving the front x member, I will probably just move that bracket up as well, but if I leave it alone then nothing will need to be done.

As for the water pump and all that, I don't know if there are any differences. I would be surprised if there were any because there is/was a ton of room between the radiator and fan. My guess is that the shroud would be the only difference (and they are listed differently in the LMC catalog).

It would be interesting to see the comparison between the 4wd frame and the 2wd frame.

Re: 4wd engine cross member

The only answer I can come up with on engine placement on the 4x was for the front drive shaft length and angle on full droop. With the stock suspension and the engine 2''rearward the cv won't bind

If so, wouldn't it be easier to just rotate the front axle to lessen the pinion angle?

I love a challenge.
