{Chevs of the 40's rents them.}

Cool rental fee ...

I sold mine for an average of $NZ 110. plus post.

The local market is tiny and I figure now saturated, so any others made would have to be pre paid. Postage to US is a killer $NZ67 last time I looked , so I really dont expect it to happen again.
You need someone to rent the chevsofthe40s tool and do the measurements etc , find a good shop to manufacture them , then return it for the core refund...
