ASTR and I looked at that...search for our posts. The backside of the AW450 has the same bolt pattern as the A440F, so the A440F's transfer case adapter would likely bolt up, BUT the A440F's output shaft is different length, diameter and spline count than 2WD AW450. *Maybe* an A440F's output shaft would swap in to the AW450, that's something he was hoping to investigate (he had the AW450, I had the A440F). Used A440F output shafts usually have heavily worn splines, so that's a factor when looking to junkyard this dealio. A440F's are also same bolt pattern on the front side, so you could conceiveably do a bellhousing swap to put the A440F/transfer behind the 4HE1, but not only is the A440F input shaft different, but nobody thinks a stock, used A440F is going to hold up to a 4HE1 even if you ignore the high stall of the A440F's torque converter. And building up an A440F wouldn't be cheap.
And I have no idea how similar an A440F's transfer case is to an HF2AV...
Does seem like it could likely work with a custom AW450 output shaft, to me, if the A440F's output shaft would not swap into the AW450.
If I misspoke at all in any of the above, please holler, as I'm a bear of very little brain.

Is anyone looking into this config for an FZJ80:
Engine: Isuzu 4HE1
Tranny: AW450
Transfer Case: existing HF2AV (FZJ80)
It seems to me this might be the easiest swap because:
1. it does not require an adapter from engine to tranny (although it may require one for the HF2AV transfer case)
2. for those of us in CA, we must obtain an engine with a build date equal to or newer than the vehicle it is going into for it to be legal, which narrows it down to the 4BD2 or the 4HE1
But has anyone looked into the basics of this config like clearance issues, etc? Has Rodney from Wholesale Automatics in AU responded to the questions about the AW450? Does he offer an extreme tranny rebuild on the AW450?
