360 Magnum correct balancer, flex, plate, converter

OK guys, I went back and reread all the posts I could on my combo....
made some changes here the package: 904 tranny
1. Street fighter 3000 stall converter with no weights on it
2. 92 360 MAgnum with the factory flex plate with no weights on it, but has been balanced you can see where they drilled balance holes
3. aftermarket 360 mag external balance harmonic balancer

I want to put the engine in today. but after rereading all the posts I am confused if I need a weight added to the converter or try to find a later magnum flexplate with weights on it????????????? or is what I have ok?
