I'm seriously considering this swap for my early A. I was looking at donor Explorers the other day at the local Pick 'n Pull and noticed a few had factory aluminum drive shafts in them. Has anybody used one of those factory Explorer aluminum drive shafts for their 8.8 swap? It seems to me you would just need to have the trans side chopped off and re-fitted with the proper yoke for your 727/904/833 and use the stock back flange to couple up to your 8.8
