Again, updating my web page info, thought I'd post a chart of my Semi Floating Dana 60 info. (Keep ckecking web page for when I update...)
The old chart was just 67-78, this one is 67-2002.
The Old chart didn't have wheel bolt pattern's, new one does.
New chart has axle shaft lengths.
This is all my info from several Spicers books and .pdfs

It's helps to have the shaft lengths, nice job.


There is an error in spline count on the Mopar passenger car D60's though.

Production Mopar Passenger car D60's did not get 35 spline shafts till 1970.

1969, and earlier were 1.5" 23spline shafts.

My 69' Hemi Charger D60:
BOM 602957 6
Date 2 18 9A7 (Feb 18 1969)

Shafts are factory style (not aftermarket) 23 splines.
Has OEM 23 spline Powerlock with matching date code (to verify originality) 2 13 69B.

1970 was the changover year to 35 spline shafts, around the same time as the swap to lighter duty Trac-Lok diffs.

It's possible Race Hemi's (like the Hurst Hemi-Darts, and Hurst Hemi-Cuda's) may have gotten 35 spline shafts in their D60's, so maybe that's where the confusion lies.

Also you have the number of lugs and the bolt circles flipped.

WOW great info! I'll double check with my book... but Spicer seems to have issues with facts and Dodge....

Thanks!

It would also be nice to have WMS lengths as well if you have access to those numbers.

Looks good tho, thanks.

One correction for the first entry, the Jeep medium truck: That should be J2000/J3000/J4000. The J20 designation was not used until 1974, and those only used the 8-lug full-float axles.

I guess my gift for the obvious isn't as good as it once was.

Thanks, I'll fix it someday...

Yeah, Spicer seems to list only the J20 for some reason.... in a couple docs to.
