I actually ended up not installing my Kartboy front endlinks because they didn't fit with my Whiteline 24 mm adjustablt fsb (I think mostly due to the bulky hardware, but that's ok). I kept the stock front endlinks, but I think they'll be fine since they're basically the same design as many aftermarket pillow ball spherical-type (whatever) end links. I also had to remove my front jack plate, but it wasn't bad. I was able to get it off fairly easily with a foot long breaker bar and some elbow grease. The difference in handling is definitely amazing. I'm kicking myself for not upgrading this stuff earlier.
