Bellhousing cover?

Still working on my 4.3 to 6.0 swap. Just wondering if I should I try to make something to cover the openings into the bellhousing? The oil pan on the 4.3 used to cover it, but the 6.0 is less wide at the oil pan, so it leaves some openings. Is there an aftermarket shroud or something I could buy? Thanks!

They sell dust covers at the dealership that I bought because the 5.3 flexplate was showing. Or I mean the bellhousing was exposed.

Do you have a part # for that dust cover? I called my gm dealer and he hadn't a clue what I was talkin about. Thanks again.
