Tuning FX Impact PP Rear Block - pin missing

I got a spare Rear Block and I did all the porting (including the Valve House and peek Valve), when all parts were ready I replaced all at once.

I noticed that I could not pull out the old dowel pin (from the R.Block) which locks the position on the brass (Huma dual port) piece so I just cut a piece of dowel I had in my drawers, knowing the OD won't hold it tight only locates the position. Temporary solution.

For now I have nowhere to shot the Impact so just sits in the case, but I don't want to forget about that pin (my improvised pin) can eventually fall out and get lost if the shooting starts.

I will contact my local dealer from where I got the Rear Block but just in case a question to you folks who did replaced the Rear Block...if you remember was the pin included in the package?
 
...You can get pins and smaller replacement parts from FX USA. ..

Thanks FX USA, Im sitting in CA/Toronto. I could email AGS to send me a pin, but feels kind of stupid got the block one months ago and raising question only now.

I know that THAT pin cannot fall out unintentionally, I just don't want to forget about it when the game beginns.

I have secured my "first aid" pin in the hole with natural bees wax, good stuff...organic ;)
