Dana Axle Identification Help

1984 Dodge Ram, it has a 2wd cab, big lift, and a W250 chassis, from what I can determine.

Are both rear and front Dana 60s?
Dana 70s?

The rear has a cover with a rubber plug, and I want to order one with a threaded plug that is higher, seems low to me.

I checked Denny's, only one in stock is $225, ouch.

Anyone have a part# for a inexpensive cover?
