It can be done without a kit. I pulled the springs, ground off the hood brackets and reattached to the hood and then installed the struts in existing holes with some fender washers, which is the hardest part of the whole process. If you really want a challenge, you can try to recreate the hood brackets from some angle iron or aluminum, but I gave up on that after doing one side and reused the factory hood bracket. There's a number of threads that give strut length and force info.
