I need an instrument cluster for an 86 xlt. I found one or so I thought ,paid for it ,and I took the old cluster out. Cluster arrived today and its the wrong one. It has a Tach on the left side with gas and temp gauges inset at bottom of tach. idiot light for oil no volt gauge. Speedometer is on right side Tach on left. So, I am in ned of an instrument cluster again or instructions on how to install this thing.
