Have a vibration...
The vibration is from an incompatibility between the flex plate and converter. The harmonic balancer is correct. Both flex plate and TQ are for the 360 but not in their existing combination. . Some of the info i gathered was incorrect and I assume, I made an incorrect assumption along the way...my fault.:banghead::banghead::banghead: Won't do that again...
Both units are for the 360 (cast date year of '79) .
The vibration will be rectified this mistake by installing a different flex plate.:sad11:
Thanks all for your help.
