I have called around to find out about swapping parts into the 14SF. So far, from what I understand, the SF rears from the 3/4 tons (81-91) are interchangable with the SF rears from the newer trucks, like the Z-71, etc. They say you can take the shafts and brakes out of, or order some, an say, 95 Z-71 and it will bolt right in place to your 3/4 ton SF after you tear it apart. Make sense? In short, the 81-91 SF has the shock mounts and the spring perches right where you need them. If you find or have one of these, just locate some 6-lug shafts and brakes and install them on the SF. My opinion would be the 3/4 ton SF would be cheaper to find than the Z-71 SF. Therefore you can do a rebuild with new parts or used, too, to build your SF to bolt right up in place of that dreaded 10B, or 12B.
