I don't know how beefy a set-up you are looking for but i opted to do an Explorer 8.8" posi swap into my '71 Ventura. I chose 3.73 gears and gained 31 spline axles, rear discs and better emergency brakes than stock. The width is almost perfect(1/8" narrower from wheel flange to wheel flange) and they are much tougher than a 10 bolt. in fact,I'm told that they're comparable to a 12bolt in strength.
It does require some fab work,and re-drilling the axles and discs for chevy bolt pattern,but it's not a tough job overall.
Food for thought.....
