Some of the unused "appendages" on the 42RH overdrive unit and tailshaft need to be removed so it will fit the stock tunnel. Of course I am OCD about how **** looks even if I can't see it so I did a bit of cutting and carving.
On the LH of the OD it will hit the stock floor shifter mechanism which I will adapt to the 42RH. The piece on the RH of the OD, it will never clear the stock tunnel. On the tailshaft, I am concerned the tabs will rub and vibrate against the trans tunnel. Heres the results.
