I'm looking at this one from DPG Offroad - either that or I'll get a local shop to bend one for me based on these pictures and some custom measurements.

Instaling the plate won't be all that hard; building around the driveshaft, springs and axles will be the tough part. Not to mention insulating the area around the exhaust.
