Looking for 78GTS int pocket lock

Hi,

I am restoring a 78 308GTS and desparately need the lock which goes on the doorpanel pocket. Does anybody know how many different model F cars had those style pockets ( I think the pockets got discontinued in 80) The pocket I am reffering to looks like a handbag which is attached onto either of the doorpanels.
Any suggestion greatly appreciated.

Thanks,
Helmut
