I made mine out of 6" c-channel. Then I welded a 4x4 box tube inside to gain height. This box tube makes a great mounting location for the 205. I trilled two holes for Duff's round poly dana 20 t-case mounts, works well for the 205 also.
This way the lower mount is inside the box tube. The sides use 2" box tube to meet the stock L brackets off the frame rails. Ah, heck here a photo...
