If you are just rebuilding the knuckle on the existing housing reusing the shims or replacing them with new ones with the same thinkness's is fine (at least IMHO) if you are putting the 60 knuckles on a different housing (like your 40) you need to measure it or build your own tool so the knuckle is centered properly. Last thing you want to do is rebuild the whole thing over again if it's causing seal failure because it's not shimmed properly. The marlin seals are better but if it's off enough they can fail. I wouldn't risk it esp when subzali has a tool.
