This picture shows where I drilled new holes to match the pattern of the greddy gasket.


This picture shows the rib I ground off for clearance for the nut. I mounted mine on the front of the core as well. Huge pain in the butt trying to get the screws into the core, back out, and tightened. If I remember correctly, after this pic I smoothed it over a bit and painted it so it didn't look so rough. I also used lock nuts. I went bolts on the inside so that if it ever loosed up I could see the nut loose vs loosing it inside the core and in the engine.
