That is the exact combo I have. Same trans gears, rear gear and tire. As I recall, you and I both rarely if ever drive at Interstate speeds. 55 mph is really the highest speed limit I encounter. The .81 OD is perfect for 65 and even 70 mph cruising. Even 75 mph @ ~2500 rpm is still very comfortable.
