Okay, after a week on the road plus two fun road trips, I finally turned some wrenches on my M1038. I got a nice used complete winch installed. I still have to add the d rings and terminate the electrical. For those of you that have not mounted a winch, some simple planning allows you to install it once, not several times!
Install lhs frame extension to lh frame rail and tighten the 3 bolts. Make sure everything is lined up.
Loosely install rhs frame extension on to winch plate.
Lift winch assembly and slide lhs of winch onto the lhs frame extension while positioning the rhs.
Install the 3 bolts (back on one gets the wire bracket installed). Tighten up.
Install the front winch plate bolts with d rings (I still have to do this), line everything up and tighten.
Install the winch control box on lhs hood support bracket.
Route wire per manual.
I can only hope this helps someone since it was quite the challenge, but yet still fun since the truck looks correct now.
Next up is the pinion parking brake, fresh tires on 12 bolts, new seat cushions, new soft top assembly and rad flush when the weather warms above freezing.
