Just a CAUTION,
I decided to replace my fuel and temp gauge today, bought a pair from MORRIS 4x4 Center, they are OMIX part # 8126919K
the threads on the old gauges are 10-32, the new gauges although they look identical and you can put a 10-32 up against the thread and it appears to be the same, is actually a 5mm x .80 pitch metric.
they came with 5 nuts to mount them, but didn't have the additional 2 to install the connector strip between the 2 gauges. So if you're doing the swap hit the hardware store for a couple of metric nuts.
