Hi Tim,
just to be sure, you're looking for the blade rams for a D2 (2S/2A blade, or toolbar blade - different rams I believe), a hardnose for it, and suitable scraper to pull behind the D2?
For the hardnose, I think all that was offered is a guard that sits in front of the hydraulic control. Not sure what a suitable scraper option would be other than one of those small Onions-type.
