Razor Dune Buggy Wheel and Axle Upgrade

In this video, I remove my previously modified stock axle and go for a 3/4" solution. Parts are still a little tough to come by, but there is a much better selection than the unique metric axle Razor put on. This is my first build-type video, so let me know what you think.

Here are the parts, minus some bolts, washers, and nuts to connect the pillow blocks and to recondition the front spindles:
