I did a little searching and found that this is a fairly common problem. my tach is stuck on 3K RPM and never moves. my question is what years tach is compatable with my 1991? and how exactly is the tach removed? normally Im good at interior work but I just dont wanna break any part of my 21 year old dash.

also my fuel guage doesnt work. this is likely the sending unit and not the cluster correct?
