The R/T just took a fatal blow

im starting to think that having a NYSpeed Fix Mikes98RT’s Truck party might be the better idea. the only thing i worry about is how acessable the parts are gonna be. if i need a new valve, or aa new lifter or something of that natrue, will i be able to run down to pep boys right then and there and get it? i have tonight to think about it at least.
