An 88MJ d35 should be a non c-clip so if a shaft brakes your tire will not walk out as easily as a c-cliped axle.
I welded mine when it was on 32in BFGs. Daily driver/ wheeler, never broke a shaft. If you weld it right, the welds will be stronger then a lockright. Ive seen many of those explode, sheer pins, fall apart, and take out gear sets.
I dont like lockrights, so I say weld it up, you could replace your welded carrier with a Detroit a much better locker later on.
Im not gonna tell you to not get a locker cause it will brake you d35. Without a locker you cant even go wheelin. Cary spares. A d44 is not much stronger then you d35, and you dont need a 14bolt for 31in tires. Weld it and go wheelin.
Dont get the rear hopping at full throttel, that brakes stuff, even big stuff. :lecture:
