KWC 1911 Floating Valve Help!

[Ujustgotsarged]

Ok so i recently got an old KWC 1911, not regulated to 1joule, looked around and redwolf do a floating valve that is compatable, and will fix the fps to site legal.  Only problem is i have looked around and i cant seem to find any installation vids or guides.  I have field striped and cleaned and lubed and sorted the hop, but other than that am lost with the modding of GBB pistols. Could somebody please help.  Sorry if this has been asked a lot before.

Thanks in advance.
