Brakes conversion, Dart 1967

Hi! Asking for a help! Trying to get front brakes conversion kit from 9` drum brakes to a full solution from SSBC.
Got two different answers from the SSBC tech, A153-1 and A13x (something) but not sure if this will fit my car. And yes, rims are 5*4,5

I have Dart 1967, 2.8L, Coupe 2D hardtop, 9` drums now (rear brakes already converted to SSBC disk brakes). So looking for a kit with a booster, complete solution. (don't know how will ship it to Russian Federation after but will find the way)

Thanks a lot in advance and have a nice day!
thanks for help...
