its actually not that hard to install, just time consuming.
also when i had the springs out i quick hit them with black paint.. what a difference!

 

The last set I helped a friend install, we took several strands of baling twine and tied the springs tight before we removed them, then took my manure loader bucket and compressed them a bit more and tied in some more twine and set the springs in place then cut the twine and all done.

 

It looks very clean, nice job!
