those do look like some pretty big gaps but it is definitely worth a shot repairing it. the stock deluxe wheel IMO looks great compared to the Grant wooden wheels. I had one on the car before I found a decent deluxe wheel. I used the 2 part epoxy on my cracks and opened them up and cross drilled like a video on you tube showed. it's been a couple years now and no cracks have re-appeared. http://www3.telus.net/68bird/steering_wheel.htm good luck.
