Hey there, just got my CCOT HFS suspension, its Thursday evening, I am looking at the instructions, and looking at the parts. I have 8 "thick collar" side bushings and 14 "thinner collar" side bushings. In the pictures and instructions, they all appear to have the same collar thickness. In the sales info they show what appears to be all the same side collar thickness and say they ship 24. I got 22 and really cant figure out where they go. I am ASSUMING the thick ones go on the perch (2x4), they say nothing about that. If anyone has recently installed this, where do they go and do you really have 2 extra thin wall bushings left? Thanks!
