Take this post and re-post it here.
Bolens - TractorByNet.com
There is also a Bolens page on Yahoo. These may yield some results, but what you are looking for is very rare indeed.
You may also google "sonny's bolens", he's a dealer in the midwest somewhere. I don't remember where off hand.
I had a Bolens and got rid of it for the parts problems. A great tractor, 2 cyl. diesel, but a major problem waiting to happen. When I was quoted 200$ for the upper amd lower radiator hoses I knew it was time to sell.
