If you aren't in a big hurry keep your eyes up for a good deal on either one. Dr Differential had a good price on new Dana 60's. I found a used 9" with very good axles, spool, aluminum housing, 4:30 pro gear and 2 complete sets of strange brakes for 500 dollars. I may never use it but the price was to good to pass up. I have a 9" in the Daytona, a dana in my Duster, and a 9" in my new small tire car.
