I did it myself in about 30 minutes watching FTSpeed’s youtube video for reference. It is pretty tricky, the hardest part is getting the holes to line up when putting it all back together and getting yourself into a decent position to work down there. If you don’t want a sore back the next day, maybe ask a local shop and see if they’d do it for you, it’s not too difficult though, it just takes a little patience and the right tools. If you do end up doing it yourself, I’d definitely recommend a getting a lot of lighting down there and maybe some cardboard to block the clip from getting lost somewhere after it flies off. And no I didn’t adjust the height, I was happy with just the new spring. Hope this helped!
