    I was wondering if a 14 bolt rear end would fit in my K5 without having to shorten the driveshaft. Also will a 1 ton 14ff bolt onto the stock driveshaft U-Joints? I have access to both a 78 3/4 ton 14 bolt and an 86? 14ff 1 ton. I would rather use the 1 ton because it is only $25 Thanks.

    With no lift, i doubt it will fit. If you have about 6" or so, you could probably get away with w/o shortening the shaft. Look at how muhc slip you have before it goes too far into the t-case.

    Measure the centerline of the axle tube to the center of the pinion yoke. The put that against the centerline - pinion yoke of a 14boltFF. Then you will know the difference.

    A 14BFF is 12.5 IIRC.

    The 3/4 ton 14ff will bolt directly in, the 1-ton version will have to have the spring perches moved and I believe the shock mounts. If you don't mind doing these things then get the 1-ton. They are the same axle though if they are the FF version.


    Your stock driveshaft will bolt up if it is behind an SM465 four speed from the mid 80's.


    I am glad you asked these questions since they never come up:grin:
