Some good info. He is talking about OEM equipment on IH Scouts. Out of production now for 25+ years. Materials have come a long way since then.

I have a TruTrac for my Impala SS. Haven't installed it yet, but am looking forward to losing the stupid Auburn cone clutch posi that is trashed.

I have a Lock Right in the rear of my 44 Jeep. It is a Dana 23 and the Lock Right is the ONLY choice for a traction aid in a 23 or 25. The Jeep has a 25 in the front. The 23 is the only full floater used in a 1/4 ton. (Traditional Jeep, CJ, etc.) I have not noticed it at all. It works great in the jeep, but does put a significant amount of driveline lash into the system.

As I noted before, a Dana 60 is very difficult to do a carrier swap compared to other rear axles. To do it right you need a case spreader in order to set preload. You can do it without, but it makes it easier. You also need a bearing puller to get diff bearings off in order to adjust backlash and preload. That is the beauty of the Powertrax or LockRight in that a DIYer with limited experience and lack of special tools can install. Taking that all into account, the Powertrax would be what I would recommend for you.
