DSE engine mount help!!

[spacepirate]

Bare with me as I'm new to working on cars by myself and learning along the way.

I went to install the engine plates onto my ls3 this morning and ran into a problem. The passenger side went on no problem but when I tried to put on the drivers side plate it interferes with the oil cooler hole you see in the pic. (At least I think thats what it is.) I can't call DSE because they're closed on the weekends but want to see what other people have done. Can I just remove that nut?

On a side note, what are you guys doing for an oil cooler? Do I need one? Can I just plug the holes? I'm running a Mast oil pan.

If you want to use a cooler I'd use the fittings in the mast pan and for plugs I think you need this Gm number 12561663.

I appreciate the input. Do I need to use a cooler?

Also that doesn't solve my main issue which is not being able to mount the engine plate to the block because of the outlet being in the way. Can I remove it and plug?

I believe the ls3 i just had built is plugged there. I believe that location is coolant for an oil cooler. I dont see a problem in plugging it.

The gm number I gave you I think is the correct number for the plug you would need but do some checking.

Thank you!! I'll check into it.
