Hello Norm,

You're correct about the steering.
I haven't given it much thought in regard to the stopper bolts and how and why it works to stop the wheels from turning out 90 degrees, but i know from your advice that its a 10mm drill hole that's 40mm out from the king pins on the flat bar.

Is that from the actual pins or the frame that they're mounted to?

Yes, the bolt length would be much appreciated.

Thanks.
