SB Cam Thrust Plate P5249637 no longer made? Only tensioner now?

Nope, the cam stays it it's position whether the plate is .010 thick or .300 thick.
How is that. The end play of the cam and it's running position are determined by a combination of the chain sprocket, the recess machined on the camshaft and the thickness of the cam plate is it not. I though the cam floats between the cam sprocket and the cam plate with each butting against the plate to stay in position.
