The hardest part was removing the old oem bushings. This kit was easy to install, you will find that the end caps will not stay closed once installed. There is a slight gap but doesn't seem to affect the operation as the pin stays centered.
Got these for my 300zx and they fit perfectly. Luckily I work at a shop so I was able to press the bushings out easily. Grease any surface the bushings touch with the lube it comes with and you’ll be set
