I just laid one on my block (LQ9), center-punched through its holes, and drilled & tapped. Pretty straightforward.
It was one like this. Not this specific one I don't think; certainly not this seller or source. But, like it.
If you look closely you'll note it's not symmetrical.

Which? Mine?
It's the LS2 one. Totally "compatible". All ya gotta do is, drill & tap the 2 holes. Piece o cake.
There's also one on a large plate that goes under 2 of the cam retainer plate screws, but some people report having some kind of trouble with it, not sure the details.
