Would This Make Sense?

You don't really need to remove the driveshaft to tell if everything is kosher. Just jack up all 4 wheels securely (using jack stands under the rear axle so the rearend is in it's normal position, not just hanging) to where the car is level and you can get underneath it good. Unbolt the driveshaft from the differential and see how far it'll slide in the trans. It should slide in 3/4"~1". You need that amount of play so it doesn't ever bottom out in the trans.
