Hello, I just purchased a 93 GMC pickup. The speedometer and fuel gauges don't work. The guy I got the truck from said he replaced the whole gauge cluster and it has a new speed sensor on it. The gauge cluster he put in has almost 300k miles on it. Should I try to purchase one with less miles? Or could it possibly be something else. The fuel gauge issue is probably the sending unit inside the tank right? Any input would be appreciated. Thanks.
