Hi there, working on neighbour's Self Propelled Lawnboy. The cogged belt was broken and the drive belt is worn & cracked. We ordered both belts from Amazon and the cogged belt was a perfect match & installed. The drive belt is another issue. Part # for the new drive belt according to the pdf parts download from Lawnboy is 110-9429. The belt we received is 3/8 x 32.375" x 1/4" deep, it's a bit too large. The original is measuring 11/32 x 32" x 7/32 deep. So obviously not the right belt. I'm in Canada and we don't have access to Stens belts. Do you guys have a different part # for this belt that would work or do I just keep ordering from different vendors until the right belt shows? There are lots of choices on Amazon and they all say that they fit the model # but I have a feeling because it's the dual belt style I'm not getting what I need. Neighbour is cheap too want's to order the cheapest thinking "they're all the same". Thanks in advance.
