Unfortunately, the '46 axle is quite different (tapering & smaller OD). And having to relocate the pads out by 7/8" on each side complicated things a bit too. Who would have guessed the '46 was set wider than the new "wide track" option Dana? 40-1/4" on the Dana to 42" on the Art Deco.
And great info in the Roadranger PDF! Gracias!
