Yes, I've replaced a Kimber one-piece full-length guide rod in my TLE II Custom, back when I owned one. My other two Kimbers already had the regular G.I. guide rod. While I was buying the G.I. guide rod, I also ordered a new recoil spring plug.
I bought Ed Brown parts:

I like Wilson-Combat parts, too, but that time I just happened to choose Ed Brown brand.
With the G.I. set-up, I can more easily field strip the 1911 without using a bushing wrench during both the disassembly and reassembly. With Kimber's full length type parts, I'm just unable to depress the recoil spring plug using only my fingers as the front edge of the plug has that guide-rod going through the front hole and the edge around the plug's hole is a bit sharp.
Using some type of tool (like the bottom of a magazine) made it too easy for me to launch that spring plug. I'm glad I wasn't working on the gun while watching my big screen TV or I could have shattered the TV screen.
Otherwise, Kimber's FLGR works fine, but, for me, I've got to have one of the 1911 bushing tools handy with a FLGR. Now, I've only got three 1911 guns (all 5" and only one of which is a Kimber now) and all three have G.I. guide-rods as that's what I prefer.
A positive thing about Kimber's FLGR is that it's made in a one-piece design and doesn't unscrew. Some folks have had their Springfield-Armory brand FLGRs unscrew at inconvenient times (like at the range).
