Are you absolutely sure they do not line up, ie not indexed with 2 or 4 holes slightly offset from even spacing around the perimeter of the ring mounting flange, or is the PCD totally different (Measurements from both would be nice to know...)? If so this would indicate that the diffs are in fact different and that we will only have the option of going with the 7" 26 spline ARB front diff fitted to the rear housing, possibly at the cost of breaking them every so often, (remeber the vehicles the front diffs came out of are half the weight of ours) , unless ARB do a redesign to accommodate the different PCD for the 7.5" R&P on the rear. (*** this is all contrary to what I have told ARB <img src="/forums/images/graemlins/shiner.gif" alt="" />)

It does however open up the possibility of a stronger front end using 7.5" R&P in the front, and whether it would be worth it to get ARB to make a 7.5" 26 spline diff only, allowing us to put the ARB diff in both ends with the addition of a 7.5" R&P set for the new rear (transferring our used 7.5" to the front). The only requirement would be to have the rear axles resplined for the later year rears.
