Some points to add, I have a Koni setup on the front of mine and spent a bit of R+D time making it work and learned a bit.

The Deluboz plates will work, but I had a lot of trouble getting them to bolt on, after I added the upper springplate to the assembly.
The little shouldered spacer they give you to center the strut shaft in the pillow ball made it so that I could not get thread engagement on the upper strut bolt. I had to make my own spacers, but this may be because of the upper spring plates I used.

If you're cheap, you can do this for about 1/3rd what the OP spent, but his setup is really the way to go if you can save the cash to do it right.
Doing it cheap means one of two things, you're either doing it ghetto as hell (my original setup) or you're going to end up doing some trial and error fitment and making some stuff like I am now.
I used ebay coilover sleeves, threw all of the hardware away but the sleeve itself and the little steel ring they give for the sleeve to sit on, the spring itself is garbage and you shouldn't use it, imo.
But the sleeves themselves are suprisingly good quality and haven't crossthreaded or seized in a year of weather exposure and occasional daily driving. Note, if you're really serious about suspension setup, the cheaper sleeves are coarser in thread pitch than the GC and would probably make it difficult to get the car cornerweighted really well.

Really though, if you're not willing to waste a bunch of your time playing with it, just buy new stuff.
I just saved a shitload of money by buying worn out dampers and having them rebuilt locally, which I was told could not be done but was able to get done for $100 by a circle track shock guy.
They work well now, even if they die soon, I paid so little for them it's no huge loss.
I'll admit that my setup doesn't perform quite as well as OptionZero's, as his is really the best way to do it and uses very good stuff.
Veilside180sx's bodies look WAY better than my current ones, worth the coin for sure imho. Mine are strong, but not the prettiest looking.
I'd have gotten his if I had seen them before I did mine.
However, if you can weld or know someone who can and don't mind doing a bunch of pain in the ass parts gathering from mcmaster and trial and error fitting, you can get a decent setup for less than you'd spend the cheapest of ebay coils if you can get a hookup on used dampers.
I've probably got about $400 in mine total and am pretty happy with the outcome.
