FX Fx Dynamic-has anyone put a King stock on one?

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.

Well, there's your answers I guess. On my GRS King, the spring is held in with a plate attached with a m3. Looks like they are changing things up as time goes by.
