ckhd Welcom to big bolt,great truck you have tires that are up, glass,cab corners,and a lot more going for you ! I have a dump truck same thing. Would suggest that you service your vacuum brake booster early in the project. Those have a leather cup that gets dry, use hydraulic jack oil from your parts store,my 2 are both over 70 yrs. old work good. My 2 cents GOOD LUCK !! Read the big service book,tells you so much !!
