I m using NE mount with force .28 I m now using a ofna vented cb. I ba e mount slid back to first hole. My cb and spur are only 3/4 together. I have tried shims but that did not work. I don't want to move tranny to fact that I don't want to drill chasise. What can I do so cb and spur come together all the way. It is totally opposite from the pics I saw I. Another thread where the poster was told to shave the collet. I need a longer collet or something to move flywheel out a lil more. Is it possible to put shims behind the collet.
