Another update:
Traded in the LNB today. Jamal wasn't there, but a nice lady there made the switch after I explained everything. I went to Lowe yesterday and picked up a 3/4 in x 3ft aluminum rod (square) and some bolts. That size (3/4) is perfect for the C120 mount. Going to do moding this weekend and will be sure to provide some details (pics/install instructions/parts list) if everything works out.
