hi jskdog,
regarding the post you made above on Sun May 22, 2011 4:57 pm.
in short, it sounds like i am in the same position you were with that orange sub5 as i am currently in with an orange patriot 2004. at least one (i haven't confirmed this on both yet) shock mount bolt holes is ovalised.
i love the frame too much to let it go. i too am considering drilling and i'm looking for something that would allow me to continue to use the existing 8mm bushing and bolt kit. how did you get on with your home-made bushes? what do they look like?
cheers,
phil
