Why do you think its cracked? Are you having shifting problems? This is a very uncommon part to be broken. If you are having shifting issues it is more likely to be a cracked or broken shift fork, synchro, etc. Sorry to sound like I doubt you, I just don't want you to waste time and $$. The parts you are trying to remove are definitely meant to removed with the trans out but you may be able to do it in the car. Good luck.

 

Don't be sorry man you sure know a helluva a lot more then I do about these cars. I sent you a PM.
