Am I missing something?
Randy - I believe the part number you're looking for is UM726. It's specified as a mid-motor part, but the bubble callout 132 in the manual points to this number in the parts list rather than UM508C, which would be for the old thinner toe blocks. The image on the page should show you that the part you're looking for is on the right side of the tree.

I had to do some digging myself to figure it out - I remember that the RF2 block was the only piece from that tree that I used in the build.
