I beleive these are MTD, but feel free to correct me if I am wrong. They are cast iron, fit an 8" wheel and weigh 20 lbs each (40 lbs per pair). The mounting holes are 5" on center. They sit 1-1/2" into the rim and have a valve stem notch 90 degrees from the centerline of the mounting holes. I have 7 pairs of these in the original boxes, with mounting hardware. I also have one pair with no box, no hardware and a piece out of the edge of one. I am asking $50 Canadian per pair for the ones in boxes with hardware, $35 for the pair without the box or hardware.
Edit: one set of weights is spoken for, 6 still available.
