Specs, tollerances and the final routing is subject to variation. Minor production tweaks happen along any assembly line. Now, this is very simple, when you figure the korean axes are built and routed for the TRS and NOT the Edge. I repeat... not the Edge.
The fact that you can shoehorn in the Edge/LoPro trem is more of a coincidence. Because again, the guitar was designed and built for a TRS not the Edge.
We can follow-up the conversation in the multiple other TRS/Edge threads
