I just picked up a 99 Ford van dana 60 rear. The BOM # is 606190-2. It has 3.54 with a factory trac-lok. The axle shafts are the big diameter, but I think they are 33 spline. It is 68" and standard 8 lug pattern. It is not a c-clip or semi floater. It is a Full Floater. Would be perfect width to match a 60 front. Front yoke is flat 4 bolt flange to accept driveline. Has a speed sensor in the center section. Asking $800 obo. For a little more, would consider putting 3.73, 4.10, or 4.30 if interested. Located in Auburn Ca. If interested, I can e-mail pictures.
