yes it is reinforced. there is a compression tube inside the spin pole just like there is in the front cross member. Additionally, there will 1/4 inch thick by 6 inch long by 1 inch wide plating on the top and bottom of the center pole to spread loads. the pole itself will be bolted onto the DS rod quite tightly hence the compression tube. it shouldnt move.

2 hard points was a challenge though you're right. i had to hand shape the back end of the pole to make sure the span was perfect, with load on the back, and the DS hole centered...
