Put 5100 and coil spring back together

I have my factory shocks off. Taking them to a shop and letting them fuck with the springs. I am allergic to bodily harm. Anything I should watch for to make sure they get put together correctly? I have them marked left and right because it is my understanding that one spring is a bit longer than the other.


Thanks!

 

The only other thing to watch for is that they don't put the spring perch on upside down.... happens alot.

 

That and the top of the shock cap is aligned right. If not it won't fit back in the shock housing of the truck.

 

All put back together. Truck is still in garage, going for a test drive and get a alignment here in a hour or so. Think I will get that lifetime deal at Firestone we shall see. Thanks for all the help/reply's!
