I just picked up a set from an RCTech member, his for sale post was from back in September so hopefully they were machined on another day than these recent blocks.
I'm sure Xray will rectify the issue. For a company that boasts doing everything in house, and making a high quality parts, this non symmetrically machined rear toe block issue will give Mr. Hudy fits. They have already had to issue a V2 to their build manual, that shows things were a wee bit hurried.
