OK, need help with my impeller replacement Alpha 1

[Road King Cole]

Ok, I decided to take it apart on my bench this afternoon. Per the manual: I took off the trim tab, removed the hex bolt inside there, removed the 2 lock nuts on the bottom, loosened the 2 lock nuts on the side as far as they could go, removed the 3 lock nuts on the top. The gear housing should now pull away... nope it does not. In a bone head move, I took my rubber mallet and gave the housing a whack and broke off a piece:



So besides that, I cannot get that lower housing off. It is not coming off. I can get the rear side to move a very little, but it seems stuck at the front (trim tab end).

Help!!!!

Thanks

Is there something else that needs to be done?
