Sorry, that housing is loooonng gone. Regarding the outboarding of postals, remember that the postal D44s are wider than the housing you had (and if I recall correctly) wider than the 86 CJ D44 also. Plus, the CJ style D44 had equal length axles, but an offset pinion. The postal D44 had a centered pinion, but unequal length axles.
And DO NOT build a high pinion D44. In my lowly opinion, it is too weak for wheeling.

And for what it's worth, I could easily be wrong on that stuff because it's reaaallly old info from my brain.
