A999 torque converter hub size

To the OP - You'll need B&M 10239 to mate the 360 LA to the neutral balanced 318 converter. If you decide to go to a non-lock-up converter in the future, you'll have to change the transmission or get non-lock-up components installed in yours. But you can use the same B&M fleplate.

I will be staying with lockup for now. Seeing as how nobody has an off-the-shelf performance lockup converter, I will eventually have one made. I dont plan on abusing the car, so the lockup should hold up for daily or almost daily use. Thanks.
