You should get the axle for $100, that's a good deal. The pinion yoke can be swapped. I know its highly debatable, but buy a new seal, the 1350 yoke, remove the 1310, remove old seal, lube new seal, install seal, lube the 1350 yoke and torque it to 150ft-lbs. Ive swapped two this way in the past and they held up fine. Most people will say to reset your pinion, which is the correct way to do it, however I've done this twice, its worked for me... but ultimately its your truck and your money if for some reason it goes bad....
