If no one wants the whole rear axle, I'd pay shipping and a few $ for your time to have the 2.9x ring and pinion.
I'm getting ready to swap out my 7 1/4 right now and the 8 1 /4 I picked up last year has some badly rust pitted gears. I cleaned them up the best I can but it would be nice to have a back up in case they wind up being really noisy.
