First Aid Kit for a Driveshaft

[peterbrown77]

I need to make a roadside repair on a driveshaft that disconnected from the transmission. I had new ones installed in June an apparently the shop did not tighten them correctly or Loctite the screws or something.

This morning, I was pulling away from a stop and - clunk - the car won't move. I looked with a flashlight and the driver's side shaft is just hanging there. I think the cap screws are all accounted for, maybe they're captive?

The car is a half hour from home and not near any auto parts store, so i need to go there "fully armed" for the repair. Obviously I am going to need my floor jack and a jackstand for safety. The car is an 02 S, with the 6-speed. Has anyone dealt with this? Hex wrench size for the Allen screws? Will I need to remove any pieces of the underbody?

I could just get it flatbedded to the garage the did the repair but it's a nice weekend...

TIA!
