    If the 14 bolt is out of a 3/4 ton 4x4 it will bolt right in. If its from a 2wd or a 1 ton the shock mounts and spring perches will need to be moved. The 10 bolt will bolt in.

    The front driveshaft will bolt right up. The rear will need a special u-joint that has the small 1310 size for the back of the shaft and a 1350 for the axle yoke. I forget what the part number is.

    [/ QUOTE ]This is not true if the 14BFF 2wd came out of a 3/4ton. A 4wd and 2wd 3/4 14BFF are exactly the same besides the shock mounts being a little longer on the 2wd.

    THe part number for the conversion u-joint is 2-1153 for a neapco joint, which is better quality than the napa joints(IMHO).

    I took my 3/4 ton 14bff out of a '76 P/U and just bolted it right in with of course the conversion u-joint, I did however notice i have alittle too much braking power coming from the rear now, i believe this to be caused by the larger brake pad surfaces (13" drums) and still running the stock 1/2 ton front disks as i haven't gotten around to converting the front yet..
