Hi all,
 Been lurking for a while and thought I'd post a question.  I'm going about 150 miles to pick up a '94 sidekick 4x4 and will be towing it back on a dolly with the rear wheels on the ground.  I'm going to bring some tools to drop the driveshaft.  What size are the bolt?  Should I remove the entire shaft or just leave it in the trans and tie it up somewhere?  If I completly remove it will the trans leak out the back (like a Ford T5 when the shaft is removed)?  Any other suggestions are appreciated.
Thanks,
WES

I just hauled in another Tracker on my dolly, the driveshaft was already unbolted but I took it out anyway.. Didn't want to run the risk of it falling out , It didn't leak anything. I think the bolts and nuts are 14 mm..

Thanks for the reply.  I'll be sure to bring my 14mm sockets/impact wrench, jack,  and some jackstands.

I have always had to use a box end wrench to grab one side of the bolt because there is not enough room to get a socket on the differential side.
