1970 Duster

I did something similar to Fisher except left the front open, but bent down instead. I also formed mine tighter to the pad. The rear bend goes under the pad there and then I pull the bracket forward and push the front bend down around the pad and it stays there on it's own. I used a soft aluminum thin gauge but thick enough to drill and tap for the mounting screws. Probably equivalent to about 3/64
The whole thing is slightly oversize so that I can slide it over to the right out of my line of sight, cuz I almost never look at it, on the street. I just bought it for the built-in shift light and rev-limiter.
Oh wait, does it have a built-in rev-limiter? Not sure, maybe it's set to 7400. It's just there in case I miss a shift..... which hasn't happened since 2004, when I pulled the V-gate out. You need a V-gate?
And I never look at the light either on the street. You need a tach?
I push the tach over to the passenger side, and say "here watch this for me, yell when it hits 6200". Then I dump the clutch, wind her up and hit 7000 about instantly, and just keep it there for between 5 and 6 seconds to about 66mph; then into direct it goes. What a hoot!
