Modified Prowler BIG TACH

We have been looking to get a different look for the Tachometer, didn't like the color of the original so we painted ours, first orange, then black, but really wanted a chrome tach. After seeing that a few folks were changing theirs and we decided that a new tach was in order. Jay Harris from Gold Coast Autotronics has put together a modified chrome tach that looks great and works the same as the original.

We purchased a AutoGauge Chrome Tach (#105-2304) and Strap (#105-3209) from JEG'S, had it shipped to Jay, he modified it and sent it to us. We installed it in just a short time and now we have a look that is very nice.
