Which Motor Mount is this

[nocardick]

OK guys,just a quick question.I bought a shell that I am putting together.It has prothane motor mounts but was missing the one motor mount that hooks to the top of the motor right underneath the cam gears.So I am on prothane's site trying to figure out which one of these inserts goes into this mount.

Is it
90-94 Engine Mount Insert Kit (Front) 13-505
90-94 Engine Mount Insert Kit (Left Upper) 13-503
90-94 Engine Mount Insert Kit (Rear) 13-506

Thanks guys

Left upper would designate the driver side, by the cam gears.
