Question non-lock-up torque converter

I bought a 727 trans out of a dodge van, 400 engine. My son-in-law got me a new B&M torque converter (non-lock-up). How can I tell if the trans is a "lock-up" or non-lock? I'm mounting it behind a built 440 in my '73 Charger. Help!

Cool

Non-lockup = input shaft has splines all the way to the end.

Lockup = input shaft end is smooth about 1/2 to 3/4" in.

Also there should be an additional electrical wire connection on the transmission case. One is for the lockup function and the other is for the neutral safety switch.
