Hi everyone I’m in the process of fitting some steel bubble arches to my Mk1 I was just wondering how to align them on the quarter panel. I’ve already bit the bullet and cut one side out with the plan to place them inside the quarter panel so there is less filler. I’m not 100% sure how everyone aligns them and as I’ve got no axle on there I’ve got no wheel centre to go off. I can line up the swage lines but the arch can slide forwards and backwards on the quarter any help appreciated cheers.
