The lowest cost for puting a used rear 26 spline LSD in the front would be if the 7.5" ring gear can stay on the diff and the rear pinion can be transfered to the front 3rd member housing.


This is unlikely as the third member housing may have been altered front to rear to allow for the larger ring and therefore the less "reach" required by the pinion.

I hope the pinion hypoid offset is the same in both front and rear to allow proper mesh if the rear ring and pinion has to be installed in the front 3rd member housing.


Will most likely be different for the above reasons (think of it as "scaling up")

If the overall differential dimensions are the same (as per the Eaton diagram discussion earlier) then a double drilled ring mounting seat is a possibility. As for the requirement for a sleeve for the larger ring, I wonder if this would be necessary given the very marginal lip that appears to be present on the existing rear diff (Daves photos), looks more like machining of the casting than an actual purposeful locating lip.
