A Chevy D44 and a 10 bolt are a wash as far as stength goes. The only reason to swap one out for the other is if one has upgraded parts or you're getting the gears you want or 8 lugs to match a rear axle. This is in the front.

A rear D44 isn't GM and is a waste. A D44 and 14 bolt rear would do you fine for your purposes. Find a set with some 3.73 or 4.10 gears and you'd be golden with those 35's. The front sees less stress unless you're hard core wheeling so take it easy and think and you should be fine.
