So somebody just deleted the thread, I dunno why, but I'll just make a new one:You can get the difficult and easy snowplows here: http://www.oharacorp.co.jp/pc/And don't worry, you don't need to understand every word on a website to be able to download stuff. Luckily for us, the pictures are in English: click them (should have taken you a second to figure out if you're little slow) and then on the next page, since you're looking to download stuff, click the text that looks like download links (the kind you've seen a million times already on the interwebs)
The easy one looks like this.
