I appreciate the update
I would probably follow EGW's lead on this, particularly with regard to the Guide Rod and Reverse Plug.
The often maligned but nonetheless 'correct' FLGR is, IMO, positively indicated for 4-inch 1911s, and I'm sure they can satisfactorily address any other issues that might arise with their 'kit'.
No doubt redundant, but I would also recommend keeping Wolff in mind for quality replacement recoil springs for the 4-inch 1911, whether Springfield, Kimber, or another brand.
