Man, that is the weakest of all weaksauces.
At least I can pretty much promise you that Alex will refund your track day fees. And I can almost help out the truck search, but not quite. My aunt and uncle have a 1984 Chevy 2WD w/350, but it's standard cab. On the plus side, they'll let it go for $1500. It has brand new AC and cooling system components, among other things. And, my grandparents have a 1992 GMC 3/4 ton for sale, 2WD, extended cab, but it's a 454 with a Banks Power Pack. Makes about 350 hp and 550 ft./lbs., but the best I could talk them down to for you, my close personal friend, is $6500 or so.
They're looking for $7500 and in no hurry to sell.
