Yes - RMS Street Lynx rear. Other mods are a Moser 8-3/4" rear axle. I looked at used Mopar 8-3/4" axles and by the time I fixed them up with new gears, bearings, sure grip and axles etc- I though it was far better to buy brand new parts.
Due to the use of rear disk brakes, you are usually limited to using the "Green" ball bearings in the axles to control end play. From an engineer's perspective, I don't like them at all because they have limited capability to take side thrust - unlike the original Mopar tapered roller bearings - that are virtually indestructable. Bill at RMS said he has used Ford (did I say Ford??!!) tapered roller bearings with the Moser axles and disk brakes - so I am going with those.
By the way - Bill is a great guy to deal with. A real treat. I drove down to his shop to pick up my suspension and Bill was very helpful. He spec'd and ordered all the Moser parts for me.
That is pretty well all the major mods I have in mind. I'm keeping the interior absolutely stock.
