To use or not to use

Actually no Im talking the larger of the two covers. As I rotate the engine I have maybe a 1/8" between the block and the head of the bolt. The larger shield has those tabs that tuck in between the block and trans to hold the top of it in place. That is where its hitting. The bolts rub almost a 1/2" or more on the cover. I tried to tweak the cover but there is just not any room with these larger bolts.

Today I went to 3 trans shops and asked if they had any bolts laying around.. No one!!! They dont save extras anymore.. At least in my neck of the woods. I then checked a couple auto parts stores, hell they couldnt even find the size I need. They are 7/16-20 x 1/2". I just need the low profile head is all. At this point Im thinking of grinding them down.

just put a wanted ad up for torque bolts
