smalljaw,
Were you not able to get it to fit at all or were you just not happy that it did not sit perfectly straight? The 604's I tried worked but theydid not sit perfectly straight. I have to admit that it was a very tight fit but I would have said they work too. The VMC 7150 also fits in the mold but you have to use a 4/0 hook in all but the largest cavity where a 5/0 will fit.
