Driver side thick end the wedge
Passenger side from rear you can see thicker end.
Pass side fat side to the rear
Update on the install. I went back and added the 2* shims to my springs to add positive castor. There's significant improvement in self centering. My truck already has new ball joints, tie rod ends, and a Red Head box. It didn't have the "wandering and skittish" issues. It would go wherever you pointed it...….and keep going that way until input at wheel the changed it. Now there is a modest resistance as the steering will come back to center on it's own. Just enough road feel. A thumb and Index finger affair. All sway bars are disconnected. I'll drive it that way for while.

ProComps Jibberiesh dept did a bang up job on the product description, I have even seen ads saying they are p[owder coated…lol no wonder they are so popular
bla bla bla nonsense aside the technical specs I got from the engineers that designed them and not the jibberish debt, so at least we know the important stuff is correct.

front axle. you want to increase Positive caster. to do that you want to roll the pinion down which would require the Fat part of the wedge to face the rear of the vehicle.
rear axle depends on which type of drive shaft you have.
for a Non-CV type you want to make the pinion shaft parellel with the Tcase output shaft so roll the pinion down by putting the fat part of the wedge facing the front of the vehicle

No that driveshaft is not backwards. The Double Cardan(CV) is at the output of the T case, and the single u joint is at the Differential. From what I understand Ford switched to this configuration sometime during production. I don't know what years. Maybe someone can tell us.

Pirate, can you do the procomp lift without the longer track bar?

Not recommended because the axle will be off center and the springs run against the hanger.
