Thanks all - it's definitely a "25 footer", typical electrical maze-o-wires and with a fair "bit-o-the-northwest-rust-out"
going on...but the cab doesn't seem to want to fall off the frame and my fat butt can stand on both running boards

The front tires are brand new Bridgestone radials and the rear duals are "new" Goodyear rock-lug recaps - probably less than 500 miles on the entire set.
It's running a small block Chev - the previous owner claimed its out of a Corvette...I'm thinking of dropping a 454 into it that I have sitting in my garage - anyone done that before on one of these?
How about Shop manuals - I've searched ebay but nothing for this year?
Oh yeah - the steering column is rubber mounted and has considerable play (not the wheel or steering, just the column shaft) is this normal?
