Driving w/o rear drive shaft - need to know

[Ace!]

I need to know, for sure, if I can drive without my rear drive shaft (without t-case fluid flying out somewhere). I pulled the shaft (slid right off the t-case output shaft), and have the output shaft of the t-case hanging ~8" or so out the back. I can't see why there would be a problem, because there is only the rubber boot of the drive shaft up against the tail cone. Can anyone confirm this before I start driving

Thanks.
