Got back last night, in the rain.
The bags are 50cal ammo cans stood on end so they open to the rear (box on top is in the way for top openers) cut the bottom out and extended them with fiberglass. Have NEVER had anything get wet inside them! I'll post a picture of them and the seat spring mount this afternoon.
The rear wheel is off a 02' Suzuki Marauder V800. It's NOT a bolt-on, the brake is 180mm not 160mm, and needs a torque arm, and the drive hub needs to be modded to fit the S-40 pulley. It's a 15 x 3.50 and takes a 140 or 150 tire fine,TUBELESS. I have the mate for it for the front, 16 x 3.00 that will go on eventually. ( it's a long story )
I am currently running a alum spoked wheel on the rear to match the front it's 16 x 2.50 with a Shinko 240 - MT90 16. The 240 is a old school tire with straight sawtooth tread and seems to roll great at about 38 psi., only thing I don't like about it is it needs a tube.
