Transmission of deceased's shares in physical form

We applied and obtained LoA based on the shares in physical form held by our father at the time of his death in 1996 and mentioned in the application.

For example he held 2000 shares of L& T in 1996 which are now 9000 shares of L &T and 800 shares of Ultratech Cement.

Please guide if will get 9000 shares of L & T and 800 shares of Ultratech Cement part of these are now with IEPF?

Do we need to take any steps in the matter or LoA is good enough?

TIA
