With the Holley mounts how many holes in the mounts are used and which frame holes are you using ? No matter how i flip spin or swap these around i can only get 3 out of 4 of the holes to line up. Also what size bolts should i use ? I cut my old ones off.

Thanks

One hole bolts into the flat bar that comes with the kit. Only 3 go through the factory holes.

I’m talking about the engine mounts that bolt to the frame. There are 4 holes in the mount but i can only get them to line up with 3 holes in the frame

This is the best pic I have of my Holley clamshells on the frame. Hopefully it helps.
