Re: [Amc-list] AMC six, crankshaft bolt pattern?

You should be able to have the snout knocked off by a machine shop while it's apart.
It's always something.
A place that does cranks would probably be best. 
If the remaining hole is too small have it enlarged or a custom bushing made.
Should be a pretty simple fix.
Hey, you could probably take it off with a grinding disc and lots of patience...and care to not touch the outer surface where the flywheel bolts up. We wouldn't want a wobble there now would we :]
I'd take it to a shop though.
