Sorry for delayed response due to Sandy.
I am not sure if you can buy front cover new from dealership but a quick phone call to them will answer your question. If anything swap your cover or find the best cover at a pick and pull.
Devs- Do it baby!
No Calibration needed when installed. Just install and go. if you want to change out the ODO readings so it is accurate to your truck you can do that as well.
***The above cluster has been sold. I just acquired a Police Speedo with 130mph. The Police Cluster will replace the Escky Cluster I was going to install in truck***
So I have another Escky Cluster FS, just with different mileage and I will post pics when I get a chance.
thanks for the inquiry ff40
