first time rear end swap

The problem with hobby shops is if you get hung up and "need something" then what?

If you have a goodly supply of tools at home, and a decent floor jack, it's not that hard. I'm assuming you are young and in good shape.

Either get a pair of those HF under-tire dollys or make something to roll on. Then all you need to do is jack up the car, unbolt "everything, and let the rear of the springs down on the ground, so the axle is on your dollys.

Pull the front spring eyes out, and snake the springs out of there. Then pull the axle on out

Even I as an old guy, "if I had the time" could do this.

Now I DID use my hoist, but for me, this means if the car had to stay there all night, no biggie. On the hoist, I got the rear shackles "all but ready" to come apart, with the nuts "finger on."

Pulled the U bolts, brake lines, etc (Go to the parts store and get 3/16 inverted flare plugs, and a "union" or two. Now you can plug off the tube on both ends)

Then let the hoist down so either the tires are on the ground, or get the axle on stands, etc

Then just pull the rear shackles. and let the springs down. EASY
