puting a 44 under there is really pointless IMO. The strength difference is non existent and the I don't know about your junkyards but I know in mine the 10 bolt is easier to find than a 44. Mine you that the 1/2 shafts are exactly the same as the 3/4 ton ones in the 10 bolt. I have a 10 bolt with 8 lug outers on my 89 burb, if I bust a shaft all I need to do is find a shaft fron an 89 blazer to replace mine(I have the 30 spline front shafts which is another story).
10 bolts can be modified to run crossover just fine you just need knuckles from an older D44.
