I did move the inboard mount and have mine at 290mm centres. Not sure why I didnt just go 300, but maybe I ordered 300, got 290 and adjusted the mount after? Long time ago now.
Anyway I do need a single hoop at 290 centres if someone has one sitting on a shelf. Ill start calling around tomorrow.
Started my Cam install tonight - made good progress and have it nearly all apart. I reckon another good afternoon and evening Ill have it done. Interested to see what difference it makes.
