Personally, if I was going to pick something to build it would be a 95 YJ. It would take some cash and a long time, but also for me the journey is as fun as the end result. I like knowing exactly how every part of my rig is built, so I know exactly what question to ask on this forum when something needs fixed [img]/wwwthreads_images/icons/smile.gif[/img].
Consider the type of wheeling you do. Full size trucks on the trails of Colorado can be tricky. Oh, checked your profile, never mind. So do you need four wheel drive to get through a wheat field? J/K, I'm from NE originally, got to pick on those Jayhawkers.
And I'm no chevy guy, but I think those are pretty weak axles; at least for the abuse we put on them. At least comparable, strengthwise, to the dana 30 and 35. so both vehicles would need an axle swap.
Keep the jeep. It's easier to take the top off; next time you're on the trail on a nice sunny day, topless, with the windsheild down (try doing that with a K5), feeling the breeze, idling amongst the rocks (or corn stubble [img]/wwwthreads_images/icons/wink.gif[/img]), you can remember the day you almost gave it up for a huge, gas guzzling ugly hunk of iron, and smile, and know that life is good.

Have you hugged your Jeep today?
