Bo used some on hand tube stock we had, and drilled out a big hole to insert this mounting thingie. That way, the weight of the transmission won't crush the steel.
Here's a close up, right before Bo Welded it into place.
Here you can see the entire thing all finished. The transmission cross member is in place, the mount is there, and the engine is also on its new mounts.
Here's a close up of the mount. The urethane parts are provided by my sponsor, Energy Suspension.
On the off chance he's reading this post, I really want to give a huge shout out to Bo The Welder, who has made so much of this progress possible! Thanks Bo!
