Hey Guys I have a strong running 83 with a crap frame and body... just bought an 85 with good body and frame but has some issues. My thought was to part out my 83 and fix the 85 but they don't look the same.... Guy I bought from told me the carb and or fuel pump was bad in the 85 so I was going to switch out but they are different looking.... One symptom is the car began stuttering/jumping after about 45 miles of driving at around 55 mph.... this gradually got worse at lower speeds. it seemed to be getting to much gas or air, don't know, very evident on hills, would jump or stutter..... does not like to idle and seems to get stuck in choke a little....Not the brightest mechanic, any advice or help would be appreciated.
