Grrrrrrrrrrrrrrrrrrrr, I have everything ready to go, or so I thought! My parts kit is an izzy kit an it has the sleeve running through the pintle pad/side plate/trunnion. My Halo side is drilled for the USGI size hole as is the other pintle pad. Should I drill out the sleeve in the trunnion block or should I drill the side plate and other pintle pad to the larger size? What size is it? How do i get a pintle down the road that matches the izzy size?? Thanks again!
