Hi,
actually we are adding a Koenig winch with PTO model 41 to a CJ3B. It is a little bit cramped but it is possible to route the driveline and the exhaust upper the crossmember. I think this is the case because of the exhaust which is not stock but build decades ago from stainless steel. Furthermore, the PTo is located a liitle bit to the back beause of the Overdrive and PTO-adapter. For the center bearing we used a roller bearing which is a bit bulky but it looks that it should be ok.
Now, I remember a post (I think the author was oldtime - but I am not sure...) years ago dealing with several winches, PTO, drivelines and their position. The Koenig was mounted quite low and in the bumper. We tried a few positions for the winch, if the driveline ends directly below the grill the winch has to be mounted "on top of the frame/bumper". For the low mount poisition the drive line has to end below the bellcrank of the steering. I added some pictures to get a feeling what I am talking about. I am not sure for the clearance with the axle but we did some tests with the left spring compressed until the front end is lifted from the ground - so it seems to be possible to route the drive line that low without colloision of the driveline with the front axle. Please feel free with your comments, experiences - perhaps someone remembers the also the post, can add pictures or has realized this setup.
Thansk a lot.
