Hi John,
I am also looking up against the brake mounting part.
But I have material enough to try and do it over if needed.
I think I make some tools to make it easier. But I will see as I am that far.

They told me the same ad the factory about welding.
I will use some test parts to practice and to find the right settings. Stick welding isn't the best for this, but a low setting and faster welding with thin electrodes, must do the trick.

I was thinking of letting them lacer cut some extra things to pimp the trike, but I wait with that till the bike is ready for painting.
