    Yes, it will pretty much bolt up.

    Search. This has been covered MANY times.

    Your wheels will fit, but you will need to move the spring perches and shock mounts. Also a conversion u-joint, IIRC

    I'm pretty sure 3/4 and 1/2 ton perches are the same. 1 tons are a little different. The SF 14 bolt should have the same distance perches. Shock mounts may be different but that is pretty minor.

    The SF 14 bolt you are talking about swapping in uses a 1330 u-joint. Your current setup uses a 1310 u-joint. Instead of replacing part of your driveshaft, they make a "conversion" u-joint. Two of the caps are the 1310 size and two are the 1330 size. Just replace your lower u-joint with that conversion u-joint and you will be good.

    The 14 bolt is out of a nbs truck, the mounts are MUCH wider. The spring perches do need to be moved. NO 6 lug 14 bolts are bolt in.
