I'm looking at building a custom instrument panel for my project bronco. It is an 85. Are the existing gauges mechanical or electrical? Will I have to replace the sensors anyways when going to new gauges, so it wouldn't matter?

 

All of your gauges are electrical and not mechanical. You will need new senders. I was seriously thinking of doing the same with my '89 but lately I have been so busy doing nuthin' I haven't had a chance.

 

Gen,
