Yes, SOR carries the unit that replaces the rear shaft cover. I believe it was used for the pumps on firetrucks. It's about $151.

Anything on the transfer case bypasses the tranny so no tranny shifting or possibility of lower gearing. I don't know how the old tranny mounted PTO units work though.

I believe your choice of the word "bypass" is incorrect. The input to the t-case is the output of the tranny. The pto gearboxes bolt to the t-case, but they are driven from the output of the tranny.

Shifting the tranny surely affects the speed of either type of PTO.

An electric motor driving the PTO would certainly make a cruiser into a hybrid. How well it would work is another issue, but it would be cool to see someone work that issue.

Yes, shifting the tranny DOES affect the PTO speed but if you are inputting power at the PTO to be delivered to the rear wheels it doesn't matter what gear the tranny is in the rear wheels will not change speed as you are applying power AFTER the tranny. I believe that is what his idea is.

With an electric motor you get most of the torque at very close to zero rpm, so as long as the motor can spin as fast as you need, you don't really need more gears than you get from the t-case and the diffs.
 
Rear Output PTO very cool!

Any guess how difficult it would be to modify the rear mount unit to work with a "Wing Mount" conversion mount on the T-Case?

To get the maximum benefit from the electric motor some form of reduction would be beneficial. approx. somewhat less than 2-1 would work best for actually driving in electric as most of the electric motors are good for 5000 RPM which would equate to approx. 100 MPH in an FJ40 which gets really scary. :steer:
