Ok, so I just got the 52' back on the road after putting it back together the past couple years..... one slight problem.

My speedometer is off about 10mph at 55mph. It's a new speedometer out of the box from Dolphin Gauges. Its a mechanical gauge, that just hooked up to my 350 turbo with the speedometer cable. I didn't notice any adjustments on the back of the gauge when I had installed it last summer.

Before I run it over to the local speedometer shop, is there anything I could be missing to try first?

Thought I would add a photo of the almost completed truck.....
