I just got my rails today. they included the spacers also. Has anyone installed the rails with these spacers? I have two short and two long spacers. Which go in the primary? Also i have some greddy 720 and bosch 1600 injectors. I have the thicker top o-rings but do i need to install the stock grommets on these injectors thanks. A pic os the spacers are attached..
