With only the one catalog listing on file and a single year of 1969 attached to it, we don't have a lot more to go on for this one. If you're rebuilding a bottom end and need to match this bolt, best to bring in the old one or your parts book reference so we can confirm it's the right length and thread before you order.
As with any connecting rod hardware, these bolts see a lot of stress in service, so it's worth checking the ones you've got for stretch or damage rather than assuming they're good to reuse.
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.
