Notice the cut exhaust where the catalytic converter wants to be. More on that later. Here, Miller has installed the T-case adapter and tranny mount, along with Advance's T-case shift linkage bracket. It, too, required modification because of interference with the Lokar linkage-actuated shifter. Again, the cable shifter would have saved us time and effort. Advance's tranny mount uses poly bushings that are exceptionally harsh at idle. We later replaced them with some rubber bushings that came with one of the company's Dana 300 tranny mounts (PN 716021).
