340 to 360 Harmonic Balancer Swap?

Everything I listed is for a 360 only.

I switched from a 318/904 to a 360/904. I bought the Mopar 360 balancer P5007301 from the local Dodge dealer and the B&M 904 360 externally balanced flex plate #10239
from Summit. Works perfect.

Lol.....This can get confusing, thats why I took all the guess work out of it and bought 360 only (externally balanced) parts.
