Those direction's suck. We need a better writeup, this is the only reason I don't have the digital dash outside in my building inside of my GLH.
Uhhh other than the #'s that is exactly what an Lbody speedo looks like.The guy who sold you that, or his father, probably made an honest mistake. That's nothing like an L-body speedo. Never was such a creature. Not in the special factory sponsored SCCA or Rally built Shelby Chargers or GLH's, turbo or NA. As stated earlier, Carroll Shelby definatedly would have used something better than an 85MPH speedo with a decal overlay if it had been available. For a faster than 85MPH reading on an Omni factory speedo, get a
'90(last year) Omni dash.It's totally different and unique,and reads to 100 MPH. BTW '90's had square outside rear-view mirrors. And an air bag.
I just got it yesterday. I have not checked for accuracy but if I check and it is reading (125 when I am going 85) then I will try and use the gear for the speedo cable from a daytona with a 125mph speedo...yea, screw them, It's an awesome part, wish they all had that. Have you tested it for accuracy? I wonder if it wraps all the way around and is accurate like the 85 MPH speedos. Cool part, wish I had it for my Masi Lbody build up.
