The waggy axle will be too narrow, it is >2" narrower than the rear.


Not too narrow. Waggy axles are 61.5" wms to wms. a late model 12-bolt is 63" wms to wms. difference of 1.5" divide by two sides thats only .75" difference at either side. hardly noticable and you could easily cover that difference with wheel spacers or different wheel offset if it really bothers you that much.
