are starter mounts to the block below where the LS4 does you just end up with an opening right there... call it the broken flexplate inspection window for all I care.
there were no wiring issues or anything it was Plug and Play
THANK YOU! Definitely grabbing it. Now that I know that, I get to start worrying about what issues I will have electrically and mechanically. Ugh. Maybe I will swap all the sensors from my current trans over since they all worked fine and no codes at all were thrown about the trans. Cheap insurance, I'd wager. Or I'll have the guy working on it test them if that's even possible.

Thanks everyone for the quick responses. Saved me some headache and a trip to NY!
