Steve, I have never once changed any brackets or linkage when going from 904 to 727 or from 727 to 904. There was always enough adjustability. This is on 67 to 75 darts, dusters or demons/sports. Kim
There is but they are different. The bracket with the 2 studs . One bends down at the studs and the other bends up. Also the rod one is longer and has a different bend. But I also made them work.
