What fits, late to early front end parts to swap?

halfafish said
I have a 64 Valiant that is going to get a complete go-through. One of my parts cars is a 74 Dart, so I was going to swap the disc brake setup from the 74 over to the 64. I am of the understanding these will fit with no issues, correct?

The next question is, the LCA's on the 74 have the tabs for a sway bar, and I do have the 74 sway bar also. Is there a way to get the 74 sway bar to work on the 64? I'm aware the late bar goes through the K frame while an early one does not. Also, I think the early A is several inches more narrow than the late A. If the late sway bar won't fit, is there a workaround to use the tabs on the late LCA's with a different bar, or ??

Just trying to figure out the options before I start taking things apart.

Use the '74 spindles-out and the upper control arms. Re-use your lower control arms and just get a Helwig sway bar assembly. Check with them to see if you need to swap sides on the spindles to avoid interference with the calipers. Sell the '74 lower control arms and factory sway bar to help pay for the Helwig sway bar.
