Main subframe done. Took me a while to figure out a way to mount (1) muffler hanger; (2) side racks; (3) fender hanger; and (4) top rack to the subframe, and add a little extra support to the flat rear part. Solution is those side plates. Those are 1/8 plate welded to the 12 gauge tubing. The plates will be finished with holes drilled for mounting the other parts.
I got a lic plate/tail light bracket from chris at boxermetal that works perfectly.
