There are two different plates now.

One has the bolt holes countersunk (newer style), and the other doesn't (older style). Not much of a variation, though. The part number I have is 12556437.

I believe the dealership only has the newer style now. Make sure you buy new bolts to go with it, your originals won't work.

Damn, did you tear everything up?

What rockers were you using again? I need to remember to stay away from those.

I had 3 lifters go bad, the roller started to go (stock). That was all. Cam actually looked OK but I am not taking my chances, so time to rebuild the top end.
