60/66 core support fillers I’m gonna bring this up as we’ve done a ton of testing and evidently there is some discrepancies on holes , some of these trucks are just built differently or something I’m at the point where we are cnc press brake bending these and guys are still complaining, I built 20 sets and every set was tested on my truck and work perfectly, some guys have no issues , some guys hustling call and say “these don’t fit “ and don’t give me reasons . So we got ways to handle this . I can remove the holes , or you guys can simply slot a hole a little and make them fit , I guess a 3rd option would be longer slots but I would need some feedback . You guys let me know what you want to do . I’ve tried to make these a really custom fit in a bolt on design , which is why we have more coverage than any of the others . Now , I can make mine shorter and take away some of the coverage and make them cheaper no problem but that’s not how I want to roll . So you guys let me know and we will make it happen .. this isn’t a bitching post this is let’s figure this out cuz I waste more time and money dealing with this than I’d like , thanks guys .c10
