in Need of an oil filter adapter for a magnum engine

There was someone needing a plate a while back and they are discontinued from mother mopar.
Magnum year ranges were 1993-2003. You list “possible years 1967-1992” after your part number. Those are LA years. The oil filter plate is different for magnum vs LA.
i didn't know that till now. thanks for the info. with that said, what is the difference?
