Wilwood brake install 1975 dart

So I recently ordered hotchkis sway bars DODGE DART Hotchkis Sport Suspension 22385F Hotchkis Sport Suspension Anti-Sway Bar Kits | Summit Racing cause the hellwig sway bar wasn’t available and it didn’t even line up with the stock sway bar endlink tabs which now is making me ask the question does that mean I might need to get a sway bar for a 75 dart I know the the spindles are from a 75 dart but now I’m not sure if the K Frame could also be from a 75 dart anyway I can check that?

The engine mounts are the easiest way to tell. Take a look at the pictures here, they show both versions (you’ll have to scroll past the other body styles).

K-Member ID Chart

ID’g the K is important, the later sway bar mounts are different. The later sway bars are a nice improvement compared to the earlier ones, but again, they use different sway bar tab locations too. Always best to identify everything you have if you have mixed and matched parts, it gets really easy to order stuff that won’t fit if you don’t figure out everything you’ve got first.
