Our catalog record ties this one to the 1975 model year and doesn't say more than that. If you're sourcing this for a rebuild, check it against the head you've got before you buy, since rocker geometry and ball-end fit can vary between engine types even within the same marque.
We don't have much more detail on this one beyond the description itself. Give us a call if you want to confirm it's the right rocker for your engine before ordering.
