No blanket, its painted blue. Do you happen to know the size and pitch of the screws and maybe the torque specs.

I have made EDITS with help from members here. Original info has been marked with "strike through text.
Should be a
3/8 course bolt Metric M8x1.25x20mm flanged head cap bolt (Thanks
Sharecropper , NDT , and
cucvrus ).
BE CAREFUL. Don't break that cast aluminum (pot-metal)
A 3/8 inch ratchet and extension with a 9/16" swivel socket should reach all the way around the bellhousing (transmission).
Turn a quarter turn, go to the next bolt. One by one in some order.
Nothing more than the palm of your hand on the ratchet.
Don't "crank" on those bolts until the gap is gone - or the most sickening "pop" sound you will ever hear - will make a really bad day.
IF THE BOLTS stop turning and the gap isn't closed, STOP and get help or ask a lot more questions!
