Ha! I'm trying to psych myself up for puling the trans/transfer. At times, it seems doable by myself, but then I stumble upon someone else's struggles and I re-think the whole endeavor. I suppose, however, that it is like a lot of things... part of the "fun" is the challenge of getting it all apart and put back together in good working order with minimal trips to the hospital.

The compressor mount is on a piece of 1/2" thick by 4" wide aluminum flat stock that is bolted to the frame with longer M12 SS tow hook bolts (the flat stock is under the tow hooks.) Since we don't have a winch, this was an option for mounting a shovel on the top. The decision to mount the compressor on the underside was driven mainly by not wanting to drill holes in body panels. Also, not really planning on hard core crawling so bashing it on boulders wasn't really a factor. I do recognize that the location isn't as ideal as perhaps in the engine compartment, but that option wasn't really something that my pea-sized brain could figure out.
