i assume the bracket is steel. it's thick square bars. i don't know the history behind it. i still haven't got the shaft apart. but i'll for sure get it shipped out by saturday. i may have to have someone come heat up that weld with a torch or something.
Instead of burning it off you can, open up that big side cover u can see in the pic, pull out the drive gear, unbolt where the shaft goes into and takeout the wormgear, and then you could take apart the driveshaft at the slip joint. and then ship it in parts or something.
