Bedford MJ 4x4 pto takeoff
 

I am looking for a pto 'take off' to drive an auxiliary hydraulic pump to power an Atlas crane.
I understand that there are two possibilities - a connection to the 4 speed gearbox or a connection to the transfer box.
I have tried all the usual ex-military dealers but drawn a blank. I have also tried the military vehicle forums. I wouldn't have though that this would have been such a scarce item.

Anybody have any suggestions?

Cheers Carl.
