LOL...you should have just bought a frame with axles and built your own!
I know, if I was still in my corporate glory days, I would have just built my own...this is the main thing I used to do. I had an entire machine shop and everybody was cross trained as a welder. I am glad I sold it all off before 2009 hit. I was just smart enough to ask myself "what is enough". I started in the marines and jumped right out onto a shovel. We are the last generation of blue collar knowledge, unless something changes. The gap between the Ivory tower of paper pushers and actual revenue producing workers, has never been so big.
