Camshaft Thrust Plate

I was talking about a thrust plate on the front. I see no reason it would need needle bearings there. Have you made this modification to a slant 6 before?
I've looked at adapting several different factory thrust plates from other engines and it's very doable with little effort. The cam gear will need to be clearanced to create the end play, but its a minor thing. No roller bearing thrust button will be needed if you use a plate....
