WANTED KW S-2 or SAR

Wanted; Kenworth S-2 or SAR, the earlier the better. Must be in excellent mechanical condition, prefer under 300K kms on rebuild. Very much prefer GM, 6V92TA or 8V71T or 8V92T. Minimum 350hp. I don't care what it looks like but it needs be either RWC or really close to, and even a months reg would be good. Shortish wheelbase but enough for a 36" bunk anyway. I will be working this a few days per week too. Looking at $20K or maybe a wee bit more if it's a top jigger.
Have looked at an S-2 tipper in Doveton and it's grouse but the money is still 7 -10 days away so i'm hedging my bets incase the S-2 tipper sells before then. An SAR would be preferable with a V8 of course but the only one i'm aware of; a black daycab tipper, has a VT903 in it and it needs a bit too much work. Closer to Melbourne the better so any leads would be much appreciated
