REAR DROPPING A FORD RANGER PICKUP TRUCK?

I have a few questions about my pickup truck. I'm planning on rear dropping my 97' ford ranger pickup truck. I'm planning on dropping the rear end so it levels to the front end. I was looking for the cheapest method. I have seen videos about just replacing the "shackles" for some shorter ones? And this should drop the rear end of the truck? Also how do I know how much to drop so it looks leveled and not higer or shorter than the front end side of the truck. What should I keep in mind before I do this? I want to know before heading out to a shop so I have some understanding of what to expect to hear. Honestly I wanted to see if I can even do it myself. As I take pleasure from extreme projects like this. Any help is good.

Buy a car if you want to be a G

Apparently you can flip the rear hangers for a 2" drop
