Is my drive shaft too short?

I reinstalled my driveshaft and it appears that it's a little short. I had the slip yoke replaced when I had it balanced. This is the original shaft to the car.

it looks too short to me. But I've seen the results of having a too short driveshaft saw off the back half of a transmission, twice. TF Patty made a mobile out of some of the more recognizable shards of the trans and driveshaft left. It also had a sign integrated with it that asked, "are you sure your driveshaft is long enough?"
