Saving Old Seagulls

I'm looking to convert my Shortshaft Silver century to a longshaft and I was curious if anybody in Canada or the states had any of the parts kicking around, I could probably get a Aluminum exhaust pipe and make it fit
Also interested in a clutched bottom end for the same

Or more easily if someone somewhat local wants to trade a short shaft silver century for a longshaft

Thanks

Didja find what you wanted I have a longshaft clutched SC but would want a clutched in return.
