Unfortunately it seems that it will be slightly more complex. The blocks differ slightly as per attached picture. The safety spring is retained by an M3 bolt (and there isn't a hole drilled for it on the Dynamic, and the rear bolt fixing hole is in a different location. Interestingly the block with 2 rear fixing holes is a new synthetic King, and the foremost hole was drilled after anodizing....I wonder if FX ran out of the right type of block?. It seems that to make this work I will have to drill a couple of holes in my Dynamic block.
