Anyone have Part Number and Source for Cam Chain Tensioner Guides?

[SFJ_RS6]

I've done some searching in the forum, but have been unable to find part numbers for the plastic/composite cam chain guides/pads, though some posts mention their availability. Thinking I'd replace mine as a preventative measure while doing my engine-out work.

Complete cam chain tensioner units, including the pads, are easily found but are $$. My tensioners are working fine, so if I can find OEM-quality replacement pads I'd probably go that route.

Thanks in advance!
