You may need to check the holes that the dowels fit into on the bell housing to make sure they are the same .496 that the Mopar block is. The last New Lakewood I did the dowel holes were .500, just like most of the dowels made out there. When I use the Robmc dowels, they were too small for the holes. It made it more difficult and the math did not work out perfect because the bell housing would have movement to the down side. Finding and old set of Mopar Performances dowels works the best.
