A518 Flex Plate Help???

Hum, I wonder if I was sent the wrong converter. I was just looking at the box it came in and it says Recon: CR94 (I'm guessing thats the part number) then below that it says TC, A518, A618, 46/47/48RE, 11". It does not say anything about RH, so could that be my problem??

AH HA!! Yes.
That just leaves the consideration about the balance.
I expect a reconditioned converter for an RH will come balanced for the Magnum.
