Yes and no. Sometimes, running changes are made, but the part number stays the same (or they add "V2" to it, but it is in the description, not the part number). For example, the C hubs were revised to be compatible with the ECS driveshafts, but they kept the part number the same. So, while they *do* fit, they aren't 100% identical. The same thing is true about the steering knuckles. They were modified to allow more steering travel, but the part number is the same. If a hobby shop has old stock (like old C hubs), you might *not* be able to use the part even though the part number is the same. Just something to be aware of (especially if you are using the ECS driveshafts).
