Here are some characteristics of axle housings that may help:
½ ton
• Stamped inspection cover “formed” over the ring gear and bolted on.
• 3/8 diam. studs for mounting inspection cover.
• 3/8 diam. studs for third member mounting.
• No recesses ground at top and bottom of housing since it used an 8-3/4 ring gear.
Early ¾ ton
• Stamped inspection cover “formed” over the ring gear and bolted on.
• 3/8 diam. studs for third member mounting and inspection cover.
• Larger housing.
• No recesses ground at top and bottom of housing for the first 481 units using an 8-3/4 ring gear. After 481 units, recesses ground at top and bottom to accept the 9-5/8 ring gear.
• 1/16th thick metal stud ring used as spacer, but not welded to housing.
Late ¾ ton
• Stamped “spherical” inspection cover bolted using 7/16 diam. studs, later welded on.
• 3/8 diam. studs for third member mounting and inspection cover.
• 7/16 diam. studs for third member mounting and inspection cover.
• 1/16 stud ring welded to housing and welded tag to housing indicating use of one gasket.
If it turns out that the housings are not correct and you need to exchange, I'll be happy to tag along.
