The junior filter is the pattern used on a jeep. I was also surprised that the bigger V8 had no filter since there is plenty of space for one.
Somewhere on my restoration thread you'll see the regular voltage regulator. Both were used on and off throughout production for some reason so not sure if there was a supply problem or two final assembly facilities. Your type with the external strap is taller as it sticks outward towards the driver and less encountered. But it is shown more in the manuals.
On the oil coolers, the early hull like mine had them separated and had the fuel filter at the rear over the final drive. The later hull had them together in front of the radiator and the fuel filter was up front with them. To make things more confusing, the oil coolers were a different pattern, and I have the later pattern on an early hull. I had to scratch build all of my oil lines so was able to make it all work. But now that you know about it, I'll have to kill you so you can't tell anyone else
