Ron - errr Jase, are you getting a kando, precision or 3071? lol.. I was gona change my mind (yes - again... ) after you mentioned the 5858 when I ALMOST bought the 5558, then after some frantic searches I came across a picture of a 5858 beside a 3076R, the 5858 is much bigger physically than a 3076R judging from pics - I said fark this aint fitting on my stock mani without clashes, I will stick to the 5558... LOL
