t5 inspection plate? is there such a thing?

As most of you know i just completed a c4 to t5 swap. My t5 bellhousing didn't come with a 'block plate' (which is what i'm finding on modern driveline, ebay, and other sites). As a matter of fact i had never heard of one until i found them 5 minutes ago. The holes for the original c4's inspection plate don't match... does anyone sell t5 inspection plates? Or is this block plate the only option (i tend to think i'd probably just modify the old inspection plate or a random piece of sheet metal instead of taking the whole thing apart...)

Thanks...
