I have just put mine on a Hudy station to compare all the RR +2mm plates that I have.
From a XB4 2wd, Brass, and one from a 2015 kit.
They all gave the same reading of 3deg.
That means the gauges are out.
I'm lost on this one.
Don't tell me Perth got the good ones lol...
Measure from toe block hole to screw hole...
Casey's and mine are out.
