I've had it with this torque converter bull ****

I've had it! I picked up 3 transmissions this weekend, all good, except one has a broken torque converter. all are 318-904 trans with the same spline pattern, but I'm having a bugger getting the front of the converter to seat inside the end of the crank. what to do. it only doesn't clear by like 1/32". the side wall of the torque converter is just a hair too big. do I need to find another converter? what are my options. how does this stuff work?
