Hello I have a 74 with a factory pto winch. Have a few questions about filling the T-case and the winch as well. Does anyone have access to a manual? 1) do you fill the pto with the same fill hole as the t-case? 2) if you look at the photo of the winch there is a drain on the bottom (hard to see) a plug half way up the winch and one higher up on the right hand side. Any suggestions would help.....
