A GM Corporate 8.5" 10 bolt is a match for the Dana 44 in strength except if you're talking a Ford High Pinion, reverse cut gear Dana 44. All other 10 bolts are the same strength as D44's overall. Where one has weeknesses the other has strengths. They've just gotten a bad wrap from the rednecks running 40's on them with big blocks and wondering why they blew up?

That said, unless you're really lucky and find a set of 3.73 or go-buy-a-lottery-ticket-you're-so-lucky lucky 4.11 axles most of what you find will be either 3.08, 3.42, and even the not-that-uncommon 2.xx ratios. GM really wanted to get good gas mileage back in the 80's.
Unless you're planning on running huge tires and have a V8 swapped in the 10 bolt might just work for you. I've seen guys break them but it was usually with big tires and under the half ton trucks they were ment to be under. Under your 2000-2500lb Sami with a little engine they shouldn't be that bad at all. If possible find a set with 30 spline axles, a decent step up in strength over the 28 spline axles they originally came with. Either that or get some aftermarket shafts for an even better upgrade in strength. Throw some 5-760X U-joints in and the only problem you should have is the ring gear. Oh, and don't use the Grenade-Lock limited slip that GM calls a Locker. POS that doesn't work well for wheeling and has earned it's nickname.
Seriously tho the 10 bolt axles probably aren't a good choice (gears & locker choices are limited, not really that strong, etc).
Have you checked on this? Just about every major locker available has a 28 and 30 spline 8.5" 10 bolt application and gears are available down to past 4.88's. I think 5.13's are even available for them.
