Yes it is only tack welded now, but before I send it would be fully TIG welded.
The reason it is so close to the transmission is because it goes right between the tunnel and transmission on its way down.
I put it closer to the transmission because it will move with the motor and trans, trying to keep it as far away from the transmission tunnel as possible. And you only have around 1/2" total to play with, so almost all of that 1/2" is between the pipe and tunnel...
I don’t think you will need to brace it on the transmission, unless it rattles....
No pressure to buy it, I just want to make sure who ever picks it up knows it is a prototype. And can send it back for any reason, no problem.
