Nice work, and very clean welds.
... I decided to save some money and build my own.
After a LOT of research I found some 1 1/2" square spindles that would fit some 6x5.5 hubs.
What did it run, and where did you find them?
Great work.
But i think that the tongue(the way it is connected to the frame) is weak comparing to the HD frame...Just my 0.2$
