OP here with an update.
I swung into an Autozone and got the OEMTOOLS compressor set (the 3rd item I linked to). I got it to work, but it was a bitt of a hassle. The main reason is because the King springs are taller. Standard height or lowering springs would be a piece of cake, I imagine.
The rear King springs weren't too bad. It was the front ones that were difficult. Not as many coils to work with, so you can only compress the spring so much. It helps if you can get ahold of the spindle/shaft and pull it out so it is fully extended. That makes it easier to get the nut started on the top.
Anyway, all four struts are assembled. Just gonna work out how I'm going to do the front lower control arm bushings (putting in Whiteline ones) and ball joints while I'm in there.
Thanks for coming to my Ted Talk. ;-)
