Replacing 9" drums with KH 4 piston discs. The flex line i have doesn't fit through the tab welded to the sub frame. The tab and original flex line have a flat spot on one side, I presume it's to keep the line from spinning. The disc brake flex line does not have the flat spot and won't fit through tab.
My question is... do i grind the tab hole round, or do i look for flex lines that have a corresponding flat spot?
