5.9 Magnum engine timing cover swap

nearpar said
I am putting together a Magnum 5.9 engine with a V-belt system for my 65 Dart.
I put a small block timing cover off a 73 charger on it, however, the Harmonic balancer
will rub the timing tab. Do I need to get the older 273 timing cover without the tab to make this work? any suggestions?

Thank you in advance

Here's my "bullet" just before install. Magnum to LA conversion ,2 belts. Bouchelon supplied PS and alt brackets, early Mopar Chrome valve covers, Chrome unsilenced air breather assembly.
