91Z28 110-145 MPH speedo conversion
#4
I am still awaiting on my 145 MPH unit to arrive. I've been looking at pics of them and it seems like the 130 marker is about where the 110 is on mine. The speedo already needs to be adjusted due to a 3.42 LS1 rear being put into the car, and I wonder if I take it somewhere to be adjusted if they can just fix it in one adjustment?

How much would that cost? I have a T56 transmission and as soon as I get this 145 MPH unit in I would llike to have it reading accurate. I though that 91 cars used a dakota digital box and it would just require some programming? I am actually pretty stupid when it comes to stuff like this though so I could be WAY off.
