Depending on how much movement you need another way to address the inward focus problem is to move the primary morror forward. I replaced the collimation bolts/springs with longer ones and this gave me an additional 10 mm travel. The GSO M7 colimation bolts can be difficult to get hold of though. Bunnings had some that worked in the automotive range and springs to suit.
