Hey there , hows it going , i was wondering if anyone can tell me a cross reference for seat appplications for a 1983 c30 single cab dually .. I heard its 1981 to 1987 that will fit in there but I dont know if that is true or not , Also a steering colum (what years will fit), this darn truck has no tilt on the steering colum need to fix that .. feel like I am driving a 1940s truck with the colum all the way up to my chinny chin chin . any help or information would be great , I really appreciate it ..
