I was searching sites and it seems the later versions including the 22RE ones are readily available. I even found a site which had 20R and the 22/20R Hybrid ones. Can't seem to find the basic pre '84 black and white 22R valve cover sticker. Anyone know where I can get one?

 

Thats going to be a tough one. Reason being is the 22r was only made 3 years before they switched to the newer style decal (I presume)

If it was me, I'd probably just slap a newer style decal on there, or the 20r/22r hybrid sticker from the metrictlc site (No one will ever know )

But in all seriousness, you may call the toyota dealership and see if they can get one. As I recall some of the newer style decals you buy are actually genuine toyota parts. If that ends up being no dice you may have to get a picture of one and see if a local graphics shop can reproduce one for you.

Hope this helps.
