Thanx MickD,
I aligned it to the rest of the guides but It aint pretty :P.
there are a few flat spots and a rough feeling where i applied pressure to align it.
I like to totally replace it to avoid any possible issues on the field (Line knicks etc).
OD is around 6-7mm based from a small ruler and poor eye sight (cant find my calipers grrr).
Will try to get a clear picture tonight but its similar to the guide on my GLX rods just a darker frame
