Hum, grinding 1/16th or 1/8th on those crossmembers sounds like a good idea. After you do that you could also take piece of bike tire intertube and somehow glue it to the radiator or the cross member to further protect it against rubbing incase the frame flexes alittle bit if you take it offroading. Just a thought.
Last night I did alittle more work on my floor pans. I sanded the whole cab floor down on Monday and sprayed rust converter in the hard to reach areas in an effort to treat any surface rust I couldn't get to with the wire wheel.
Then last night I put 3 coats (2 thin and 1 thick) of self etching primer on everything that's going to be coated with herculiner. This was probably alittle overkill but I figured it would give the herculiner something nice to stick to since I did some welding and rust converter and some spots still had stock paint on it. Next step is applying the actual herculiner which I can't wait to do.
I also took the winch off last night and removed the PTO shaft. I really wanted to rebuild it even though the previous owner said it worked fine but now I'm thinking I might sell it so I can buy a cummins for it. Plus I'm kind of scared to operate the PTO winch because I've never used one and have heard bad things can happen if you don't know what your doing. Anyone interested in the winch? Ill sell the winch, frame extensions with bumper attached, all winch mount flanges, the pto shaft, in-cab pto shift handle and linkage and pretty much whatever else goes to the winch.
