Harmonic Balancer and Timing cover

This is what the summit site says about your new timing cover,
"Made from quality materials for durability—and thicker than typical timing covers"
So the question is, how much thicker? How much more room do you need to fully install your balancer? Assuming the balancer is the stock unit you removed.
Is it possible to compare the profile with your old cover and find the difference?
Once you know that it may be easier to find a solution. The easiest and least costly would be to gently grind a small amount from the timing mark boss if it's possible without grinding through it. Good luck.
