    At some point a PO had the complete exhaust redone and brought it out the driver's side, but the big deal is it was run such that I can't even install the Koenig PTO on the back of the transfer case. So while I was eventually going to replace the exhaust system, it becomes a higher priority if I want to move forward on the winch. I know I've read where the front part of the exhaust at some point has to be moved some, but I'm not clear on how far down the initial pipe that takes place. I was thinking about getting the complete system from Walcks but Carl said he is not sure if it can be modified locally and work. So I'm trying to decide if I start with the initial down pipe from him and then let local place connect to the muffler of if I should have them go all the way from head to muffler. I am going yo get the muffler and last section from Carl but looking for input from those who have done it before.

    Things are definitely tight between the bellhousing, m/c & exhaust pipe. I managed to make it work with the exhaust pipe moved out about 1" at the bottom but I don't have a stock m/c, mine has a bit more room around it than the stock unit. As I'm sure you know the koenig installation instructions called for moving the exhaust pipe under the tranny crossmember.

    Two things, as posted before.

    1) The front down-pipe can be heated near the manifold connection, and bent slight outwards away from the engine, and if necessary (see#2), very slightly downward.

    2) Then the long horizontal run must be positioned below the transmission crossmember if it is not already. This may require slight bending, and a short middle extension. Later models were routed this way from the factory.

    Then the space above/inside the crossmember is available for the PTO shaft to occupy.

    This is all explained in the Koenig manual which Howard linked above and I sent earlier. See Page #7. In my experience, some minor tweaking with the torch may require several small adjustments, but will work in the end.

    Yes, I've read that but not sure how far down the front pipe before starting to change. The current exhaust does go under the crossmember but then bends up as it goes back and the muffler is on the driver's side before the differential. That up bend goes where the PTO should clock to. And with the muffler where it is, I can even get the parking brake spring in its normal hole in the body.

    Apparently, the exhaust that both Walcks and KW sell is the exact same (even use the same number) and it must be based on the early version. Based on the comments on KW, it needs bending, running under, etc. The Koenig doc says starting with #93763, which puts it somewhere in 1959. But I guess the outfit making the exhaust is not aware of the change and only offer the early version. So I'm thinking only get the muffler and tail pipe from Walcks for now with the sale this weekend. Then visit a local to fab the rest.
