Did some searching on this most excellent forum...
... and got some great tips for a rear rack that would accommodate my Wolfman Tail Bag. This one is a simple piece of 3/8" ABS from Tap Plastics with the appropriate hardware from McMaster-Carr (M6 Size, 70mm Length, 1.00mm Pitch bolts) and... here we have it... (btw, I have lots and lots of nuts to fit these bolts if anyone needs them... just pm me)
One thing I like about this rack, other than it fitting the big Wolfy Tail Bag, I think I can get a dry bag with tent and sleeping bag either horizontally across the seat behind me with the tail bag installed, or run vertically with no tail bag.
Cheers!
