I did not go back to see what tranny you were running, but there is a consistent issue with cracking bellhousings in "newer" tranny's that are solid mounted. I am speaking of 4L80 and 4l60. Both of those tranny's require the dust cover be installed as it is a structural component in the tranny and are recommended to not be solid mounted. I would poly mount the tranny and motor, run a cross member for tranny and support for the 205. The tailhousing is not designed to take the leverage that you will put on it by leaving out the transmission support. Just my opinion, but for the little effort that building a crossmember and support takes it beats getting pullled of the trail with major damage due to failure in a casting.
