The Chopper Compendium

Ironically I now have two Sporty's but everything is at somebody else's shop. I'm looking for dimensions or a pattern for the old ironhead front motor mount plates, 57 to around 82 or so before the change to newer version with the 'kinks' in them.
Thanks

Do you still need these templates?

Here are the templates from my 1977 Ironhead front motor mount plates.
