sure, i would be willing to help this weekend is my last before i go back to work, the only thing i can think of where you may have issues is pulling the pins for the guide rails and rolling in the new chain, whan do you plan on doing this? what color are the old rails? the chain is one single unit that works for both sides, only other thing i would add to your list is the chain tensioner. the only other thing about your rails is you can only do 4 without removing the front cover. two upper on drivers side, main rail tensioner at passside and upper on passenger side.
