If you take some pics and post them I am sure we would enjoy it and be able to help much more. Do the bolts not fit because there is a spoke in the way or is it because they just don't seem to want to go through the rag joint. If there isn't a spoke in the way then just punch the sucker through the rag joint. Maybe put some leather on the palm of your hand to push it in or just take the slow route and twist them in. You will get there eventually. Eventually I would suggest you stop using the rag joint and move onto some kind of sprocket adapter. The rag joint is going to fail or cause a failure sooner or later.
