Does anyone know what the bolt sizes are, if they are fine or coarse threaded, and if they are SAE or Metric bolts. Thanks in advance

Just to be sure, it is a bolt on the perimeter of the outer cover? If yes, the majority of them are going to be an M6 x 1 x 40, and ONE will be an M6 x 1 x 45 (located at the front center. They are Flanged hex head bolts (8mm hex). I am going off of memory with the thread pitch, so it would be best to remove a different one and take it to the local ace hardware and verify. You can probably just buy one there as well since Ace has a great metric selection. They don't need to be a high grade bolt as they only get torqued to 6ft-lbs. Make sure to apply Loctite 243 (high temp and oil resisant) to ensure they don't fall out.
Whatever you do, do not get stainless steel bolts. Stainless steel and Aluminum will have a galvanic reaction and accelerate corrosion. Nickel plated is ideal, or regular steel otherwise. If you want some stealth mode you could use black oxide treated bolts too.
