Hy redwing, it happens to the best of us once in a while, one trick an old transmission man taught me years ago was to shim between the fly wheel and converter, there must be some clearance but keep it as close as you can. I have always done this since, sometimes three washers will fit in there and still have some clearance, the only other consideration is that your bolt still has adequate thread engagement, (might have to use a longer than stock bolt), that way you get maximum pump drive lug contact, hope that helps.
