Dana Corp is an independent manufacturer of automotive components,
traded on the NYSE under ticker symbol DCN.  They have a home page at
<http://www.dana.com>.  The company was founded (as C.W. Spicer) in
1904 by Clarence Spicer, inventor of the universal joint bearing his
name.  Charles Dana joined the company in 1914.  The company is not
now, nor has it ever been, a subsidiary of an auto manufacturer.

Actually, no.  The Dana model 20 is a transfer case.  Both of these
axles were AMC corporate products, probably built using technology
licensed from Dana.  Certainly, the limited slip versions were
designed by Dana.  According to Dana's 100th anniversary book,
available in PDF format on their web site, Jeep in the 1980s awarded
Dana Corp an exclusive supply contract to produce both driven and
non-driven axles.  This corresponds with the transition from the AMC
15 axle to the Dana 35 in Jeeps.  The D35 has no applications other
than Jeep, commencing in 1984, according to US Gear's application
chart.  It is entirely possible that AMC transferred the Model 15
design to Dana.

Armand says,

Apparently Glen and Randy both agree that the parts from a Dana don't
interchange with the AMC 20.
Is everybody in agreement with this? any personnal experiences to relate?

Thanks all,

Armand
