Dodge and Chevy front 60s are very similar, and in many cases fairly interchangeable - both parts and entire assemblies. Differences do exist, and some are:
1) All Chevy 60s are kingpin knuckle, whereas early (79-93 ) Dodge are kingpin and later (94+ ) are balljoint (and undesirable)
2) All Chevy 60s are internal style lockout / drive flange bearing hubs, whereas early (79-89 ) Dodge are external, and later Dodge (90-93) are internal.
3) Dodge and Chevy outer kingpin knuckles are very similar, and either will bolt to the other axle, but they are not identical - tie-rod placement is different - the Dodge mounts the TRE about an inch and a half higher. Tie rod end taper is the same for all Chevy, Dodge up to 93, and 78-79 Ford. 85+ Ford is smaller to 99, then 2000+ Ford SuperDuty is larger and SupeDuty specific.
4) Chevy leaf spring pads are 3 inches wide and 32 inches apart (center-pin to center-pin), Dodge are 2.5 inches wide and 32.5 inches apart.
5) All SRW Chevy 60s are 69" wide wheel-mounting-surface to wheel-mounting-surface (wms-wms). Most SRW Dodge are 67" wide, although some are reportedly 69" wide too. A Dodge DRW 60 is 75.5" wms-wms.
6) Chevy rotors are 1.5" thick, early dodge rotors are 1.25" thick, but the calipers are identical. Dodge 60s from the CTD years (90-ish to 93) have 1.5" rotors.
7) Dodge 60s from the CTD years (90-ish to 93) have a higher tie rod location than the older Chevy.
