Blue??? or you looking for exact color?
you have to drill a couple hole in the original pillar and the kit should have some plaster screw lookin things you put through both the new pillar and old pillar. I would recommend going to DieselManor.com if you have problems. They have a pretty good instructions on there for the pillar and guages
Did they mean Ford never made a blue interior ever, or just never after they released the Powerstroke?
Reason I ask, my 91 F150 had blue interior. Think it was darker though.
