Sunday update...
Back of 4L80e with a temporary brace. The six holes in the trans are not symetrical....
Here is a close up of the 3/8 plate that bolts to the trans/xfer adapter... It's welded to the tube crossmember and then boxed in... then some overall pics
Plent of room on the driver side for exhaust... none one the passenger side as the transfer case is clocked up and is only an inch from the floor...
