Prior owner replaced the Ignition Lock cylinder and it is a VW key type not Porsche. Any ideas if there are aftermarket version that have the Porsche key type?

I see someone is selling a NOS for over $500 on Ebay but that is just too much - I assume it is hard to find.

Aftermarket will be fine and I know the tumblers won't match but that is ok - maybe I can find a locksmith to tune them to the rest of the lock cylinders I have.

I have an early ignition lock cylinder, I bought a complete matching set of handles and locks, most of mine were long lost. At the time I didn't know it was the wrong year ignition lock. I need to get my late model cylinder rekeyed to match the rest. I don't know if I can just switch the pins between them. I am hoping to do that this summer while it is too hot to enjoy driving.

70-71 locks are VW Type 3 style BUT Porsche key part is unique.
