I am still working on my STX38 replacing missing parts . I got all the parts but I found out my ignition switch was not any good , So I went thru eBay and got a new one which is a brand new original JD part TCA15075 AM101561 NEW OEM but when I got it ,It will not fit into to hole in the plastic shift quadrent (to big around). Acording to JD parts lookup this is the only switch used on STX . Does anyone have any idea why and how to get the right one that will fit. Or should I just drill the hole in the quad bigger?
