Heres one for 625$ http://greenbay.craigslist.org/cto/2713826947.html
Its in wisconsin, not sure how far of a drive it is from IL. Could easily part it out and get the front axle for free...
Not unless you can figure out how to mount a spring perch halfway on the cast pumpkin and on the axle tube for the drivers side
I know several people that have done it. You need at least a 4 inch lift or the pumpkin will hit the crossmember.
OP is down by St. Louis. The truck is in Door County. I would guess 8 to 9 hours drive.
