904 to 5.2

Ok I must be doing something wrong I swapped out my 833 for a 904. I was installing the trans this afternoon and ended up snapping off one of the ears on the engine. I dropped the trans and found out the torque converter snout is to long. When trans is mounted its about a 1/4 off all the way around. I looked at magnum swap and it doesn't say anything about changing the converter. and Ive been searching for a while now. Any suggestions or a part number for the correct converter?
Thanks
