Can anybody tell me what ring and pinion gears I have? The tag on the dif cover said 41-11 3.73 ( assuming this is 3.73 gears). The ring gear said 5 15 73 (assuming date) DANA 18515 83d37 41-11 and then there was a 792 on the ring and pinion. So what do I have? Also were can I get a 4 speed shift knob label? Thanks, Mike
