74' super beetle seats HELP!

[paysonsmama]

Hi all. New to this forum, I am looking for help. I bought a 74' Sun Bug with the retractable sun roof, my biggest issue right now is that it didn't come with any seats! I have been told that there are two types of seat tracks, but mine seem to be different than both types! The floor pans have been replaced previous to me owning this car, and my only thought is that the floor pans are meant for a mexican beetle? If so what can I do about seats? Can I buy mexican seats? How can I find out exactly where these tracks came from and what year seats I should be looking for? Thanks for any insight you guys can possibly offer!
