See what's available for similar size and configuration vehicles ie Jeep JK, etc. If dimensions are provided, take your own measurements and compare to see what works or what might could work with some minor tweaking.

Some square tubing, some extruded steel, some measure once, cut twice-ing, a few zip-zap booger welds with an el-cheapo Hobo Fright Tulz lightening stitcher and badda boom badda bing.
