Now that I'm putting everything back together I'm revisiting something I had forgotten about. On the 1978 98 it had a TH400 transmission with a bracket that hangs off the back of the transmission, which connects to the back of the catalytic converter. There's two rubber grommet spacers that it had on the mount, but the originals were pretty rotted. I need to get new ones but it seems I misplaced the originals. Does anyone know how big they are supposed to be? Thanks.
