32 Cabriolet

Earlier this year I imported this car into Australia and have since tracked 2 previous owners. Last one told me he had bought the car from a guy in Ohio probable first name John who built it using a body he got from Canada.
Car was probaly built about 1999.
When he bought it there was a 5 window as part of the deal.
To register for road use here we need to change a few things and it would help to know the build details.
Car is Mint green one which was for sale in Alabama and on a few Rod sites for most of last year.
Any leads, addresses, email or phone will be appreciated.
All the best.
Clive.
