Jusy wondering how strong that will be? Side to side. Seems like a lot of force on a nut and washer. Compared to the orginial. Where's it's bolted direct to the cross member. who knows. Just seems like all that force is now on the sides of the nut. Bet that Lakesideroadster guy would put it on his cad system and show ya a bunch of nice colors and stuff.
Wish I was there I would give it a good wiggle test.
Do like your work though.
