Search for the bullet hole practical shooting club (BHPSC) on face book. Meets weekly on Fridays at 6 pm for a USPSA match. There are a few CZ shooters there who may be able to help. I'd help you but I just had twins and am housebound.
If you buy a new hammer strut and pins you won't have to go through the pain of driving out the old ones. You won't have to dissasemble the sear cage so it's pretty much a drop in part without fiddling with any of the difficult springs.
