Scooter bought that one I think and welded it up just to make it stronger. I almost went that way, but the cheap in me and free metal. Took a couple months but we did it.
If you have cash, there is a swagoffroad.com something like that, they have it all CNC made brake, and you weld it together. It is nice, but some fair size angle iron, piece of plate and you can get by.
Scooter and Chadrock gave all the metal sizes, or close enough Chad could copy Frank's version. I can take pic and measure when he used if you need and PM or email to you.
