Grigg, Ed and Others, I will try to get a better look at the top of this Aux Box tomorrow and post additional pictures. I do see that this box does NOT have any provision for a PTO drive. Hmmmmm, it also has a speedo drive on the output side of trans, that is OK and probably typical. This box looks to have a lighter front mounting bracket and also the big heavy rear bracket. The U-joints look rather antiquated and may need to be retrofitted to a more modern version. The shift linkage looks very robust and appears to allow the shift tower to be mounted to the left side of the main box shift tower. It may be a bit congested as I also plan to relocate the dump shift levers to the left side of the main box shifter. Thoughts please.....
