The one list is from your dad, the other is posted by Ken at the 3FE site, I just cut and pasted. 62 specific huh. Sorry for the confusion then.
What are the differences (besides the 4wd actuation)? School me.
Ah, cool, it's all great info and I was just giving you a hard time.
I doubt my memory would be adequate to properly "school" you on the differences, but in general an FJ62 transfer case has the same general construction and mechanisms as the 60s but almost all of the components are different.
For starters, almost all the parts on the list you pasted are 62 specific since they relate to the interior components of the 62.
So lets follow the power through the case:
First off, the gearing is higher on the 62 case, that changes all the gear sizes, tooth counts and ratios.
The input gear has an o ring grove rather than a collar.
Rather than a pto gear, the 62s have a spacer (or is that the other way around? 60s have the spacer and the 62 have the gear? I think that varied with years)
The idler shaft on a 62 case is some 15 or 20mm larger than the 60, that changes the shaft, the gears, the bearings, the o-rings, the thrust washers and the front and back case.
The hi-low assembly works the same way, but has needle bearings rather than bushings. so that changes the shaft size and obviously the bearings.
The rear output collar is different, the speedo gear, spacer and washer are different sizes to account for the different gearing in the 62 axles and case.
The speedo assembly and the associated o-ring is a different size.
The output flanges are a different pattern form the earlier 60s (like Johnny's).
Up front you mention the vacuum shifter, which actually does not change as many parts as you might think, there are some extra holes in the case, but the engagement shaft is actually the same, just on the 60 there are not threaded holes for the diaphragm housing to bolt to and the shaft has an oil seal and dust boot on it, rather than the housing like the 62.
There are some other minor differences in the sensors and the cases, small parts, but that pretty sums up what I can remember off the top of my head.
