Our records show this part appearing across catalog listings from 1969 to 1970, but we don't have a confirmed model or engine family tied to it in our data, so give the shop a call and we'll help confirm fitment against your gearbox before you order.
The entry we have on file is brief. If you've got the old gearbox apart and are trying to match this up, having the internals in front of you or a good parts diagram handy will help us get you the right piece.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
Sorry if we got something wrong here. If you think this information isn't correct, .
