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.
