When I saw "CNC Dude" replied, I was thinking maybe that you cut them out and sold them, I was wrong...
I did some searched, and it seems more important for an auto trans and clearance for flex plate maybe? It doesn't seem to be a big deal for a manual trans - which is what I am using.
I also haven't found anyone saying they left it out and had problems, yet, so maybe I will not worry about it, I can mock it up and see how it clears before installing too....Thanks
