Ted, When I was upgrading everything for the new motor set up one thing I wanted was a CSR shield to have a clean look and avoid the hassle of a blanket and separate flexplate shield.
Well, I ordered one from Summit, trimmed my case, and not one of the bolt holes would line up. I even went so far as to throw the trans in the back of the van and drive down to summit and test each each of the remaining 3 they had in stock.
Not one of them would allow me to install all the bellhousing bolts.
I gave up on the thought and just installed the blanket and flexplate sheild.
ANd, to be honest, after seeing some of the pics that have been posted over the years of those shields not containing a front drum explosion I feel 1000 times better about that decision. (even though I now have a billet drum)
