Sorry Tim, Not all years, look for the newer years around that era. On any of those bikes Tim mentioned. They changed the oil passages from the the older 70's to the newer ones. You have your old one when picking up a new one just make sure the oil passages line up. A quick pict will confirm. A brand new one can be achieved at dratv.com

If they say it will then I would take their word. I know on my 79 I had to have the right gaskets. For its year, when I bought them.

Thanks for the info, Jenn. Are the differences visible in a photo? I think Ive still got a few, I might be able to help him with, if they are the right ones. If I email him good photo, will he able to match it with his?

It should be pretty obvious, the holes are bigger. I unfortantly do not have my 70's anymore. I just know I ran into this. It may not be that huge of a deal , but you need the oil for the topend. Is the only reason why I bring this up.
