Just a quick question im not sure whats the go with au torque converter and fly wheel but do u need to leave them matching up or could I use one of them like the torque converter to use in the el with my previous balanced fly wheel

They wouldn't need be matched as a pair... The Auto runs a flex plate, not a fly wheel... I haven't looked at a flex plate to see if it is even balanced... You can replace your torque converter with a new item so it must be balanced as it's own entity and then bolted to a balanced motor...

Cheers,
Tim
