Got the bows blasted and primed over the weekend. Am now trying to figure out which ones go where. They are all different lengths but all of them seem too long as if they are for a later model wider sub. Should I try to get them all screwed into their respective places on the roof ribs before starting the headliner install or should I try to fit them up as I install each individual headliner piece? Any suggestions Tim or PeeWee? Weeds
