diff ID help
I'm in the process of switching out diff's. I would like to identify the diff going in. The numbers on the bottom of the diff case are kind of spread out and read AW....W...357....E...1.
Inside the housing the spider gears that the side gear yolks go through have a smallish friction plate on both outside ends of the large spider gears. Does having spiders gears make this a 'peg leg' diff vs some kind of semi positraction unit?. Though the '63 shop manual shows the spider gears it doesn't show the friction plates.
The diff was acquired some years ago. If memory serves this diff was supposed to have come out of a '72 year car. Can anyone confirm?

I'll make a stab at it.
AW = 308 posi
W = built in Warren Mich
357 = day of year
E = Eaton posi unit
1 = built by first shift of day
I believe the year comes from cast numbers on the nose of the diff

Would you happen to know.....???
I just bot a 58 that is going to get a frame-off, then go for top flight.
I have done 3 top flight midyears but this is my first solid axle.
My question is with regard to the differential. My car is non posi. Can I just replace the 3rd member with a posi to accomplish this? Do I need new axles? (I understand that mine will not have the oil baffles inside.) Thanks.
