Ok. I used the video to exorcise my 642 and it was great, BTW. It only took 20 minutes for a non-handy guy. When I went to perform the IL-ectomy on my 629 and 610, I saw the the basic strip is way different. I have searched the site for two days and can't find anything. I know I'm pathetic, but can somebody provide me A-Z instructions on the procedure for external hammer guns?
