The BOM # on mine rear axel was 605242.  
When I took it in to have work done the guy looked it up in the Dana files and it 
said it was a 1985 CJ-10.  He had never seen or heard of a CJ-10 before that day.  
But, the numbers in his book said that's what it was.

Here is the info on the BOM # from the DANA Site.  The BOM# is for a Jeep 70RA
