The axle/diff setup I ordered (ex USA) was a custom order:
> Moser (Dana) 60
> 3.73:1 Detroit Locker
> 35 spline alloy axles
> Forged 1350 yoke
> Moser Alloy Rear cover 356-T6
> Standard width
> Std 4.5 x 5 x 1/2 studs
> Ford axle housing ends and axle bearings

[the reason for this is that Wilwood have(had) VERY limited choices for Mopar rears. The Ford axle ends/housing opened up significant options for the rear brakes]

> Brakes: Wilwood 14 inch slotted vented drilled discs, hat/hub units incorporating internal park drum-brake assembly, 4-Piston calipers.
