I bought one years ago. Stupid needle was not accurate and was bouncy. I took it back to Advance Auto (that or AutoZone) and told them the truth. They gave me the money back without question... kind of like people return them all of the time or something.
I got the auto guage unit in the Duster. It's the big 5 in.
one. It has the shift lite in the guage face. Works great and
was a good price.
You won't be disapointed with it.
