I need struts on my 2002 GTP with 137k miles because the right one is hopping when I hit anything rough. Not sure what else is wrong with it, but the boot has separated from the shock. I've found a number of replacement parts, but don't want to change my ride height or spring rate (nor break the bank). What about these from ZZP:

Or this kit from Am Autoparts?:
