Our catalog record on this one is thin - we see it in two entries spanning 1971 to 1973, but we don't have a partner description or extra spec detail to lean on beyond the name itself. If you're chasing this for a rebuild, give us a call and we can confirm exact fitment before you order.
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, .
