The Dana 44 front and the Dana 60 rear should have the same ratios. For some reason GMC used Dana 60's and Chevy used the Eaton(HO52). I think the Eaton is a stronger rear axle just a little harder to get parts for especially brake parts. That can be solved by using 14 bolt brackets and converting to rear discs on the HO52. If the ratio is close, I would keep the HO52.
You could run a 4.11 rear axle with a 4.09 front and not have any issues if the driving surface allowed for some slippage (you shouldn't be in 4wd if it doesn't)!
