Hey everyone...My Vector doesn't have upper bogey wheels. I have no idea why. It has in place the parts below. The wheel is the one I just purchased to put them back on the sled but it doesn't fit using the parts below. I was trying to find a pic of 'Bracket 7' (8JB-47419-00-00) to see if that is what I need but I couldn't find one. Maybe this stuff was installed by the previous owner when he studded it. If anyone knows if I need to order the bracket 8JB-47419-00-00 to take place of that round metal piece in the pic I would greatly appreciate it. Maybe someone could show me a pic of what pieces I am supposed to have. www.babbittsonline.com/oemparts/a/yam/5003c8b1f8700212fc84362e/track-suspension-1 Also, the metal around my rear mono shock mount hole has been scraped down by the backings of loose studs. It looks like I'll have to replace the entire shock. Anyone know what my best approach to this problem is? Upgrade shock? Buy used and send for re-valve and big boy spring? I am in the process of putting a pre-studded track on now. Thanks everyone.
