How hard are the yellows to install. how much modification is needed to put them in. I've swapped out a set of stock ones and replaced with kyb's so i know how. Ive heard that they have to be modified to install though.
Dude I "KNOW" you didn't search on this one or you would definitely know what the deal was putting these in. click the link at the bottom of my Sig it will tell you almost everything you ever wanted to know about doing this.
