brien, this is the "mark" that Stu mentioned. i made the deal on two of those 17.5s today. will probably pic them up sat. and get the rubber off to check there condition. I've been going back and forth with Stu a little so im not sure what your status is on wheels but i will get them non the less and pass them off if you still need them. if not, no big deal. plus i will be checking my top secret yard sat. to see if i can round out the set.
