I'm not disputing whether a 4.3 kit exists, we now know it does
obviously there will be no gap with a 4.3 kit on a 4.3 slide, we were talking about 5.1 kits before you posted that link
what I am disputing is how you can say that for a 5.1 kit you need to put it on a 5.1 frame with a 4.3 slide which is false information,
scroll back a page
the OP started talking about a 5.1 kit as it was all he could find, someone else said that he needed to put that 5.1 kit on a 5.1 frame with a 4.3 slide, at that point of the conversation, no one was talking about 4.3 kits as it's existence was not revealed until you joined in
