Rear Main Seal?

[MasterSe7en]

Ok so i just got me a $955 clutch/Flywheel combo+$100 for my ZR1's but heres my question, im gonna be changing the clutch this week sometime, and i was wondering, do i have to drop the oil pan a little bit to replace the rear main? cuz from what it looks like the seal is inside this metal bracket thingy that looks like the timing cover....can that thing be removed without the oil pan being dropped?

oh and the Clutch is a LuK Pro Gold 04-903 and it came with a high performance SFi Aluminum Flywheel not a bad deal eh? i was selling the rims with tires for $500 some dude with a white 94Z from portland ME.
