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

It seems as though the powers that be think the chain tensioner is mandatory now. Is there a reason a guy can't just buy a new small block cam thrust plate (P5249637) instead of a chain tensioner? Looks like the Mopar Performace version is even hard to find. I could only find the Mancini version. Mancini Racing Timing Chain Tensioners
