Well, BUMMER! That didn't help us. Not sure how bad it hurts (it is still a 12 bolt and it does still have the E in the stamping on the axle tube) but I didn't find what I had hoped for. You guys were, of course, right on the money that it wouldn't be hard to remove. ;-) Just took a little time. I posted the pics. The cover is still off so I can get other pics if there is something else you'd like to see.
