68 Barracuda Front Suspension Rebuild Kit

You could, but I would not bother. There is nothing inherently wrong or weak with the 67 down idler cantilevered beam design. Your problem is the cheap or worn out idler arm. I run that design on my 66 Barracuda and on my 67 383 K Frame, but use a kit to make it a Roller bearing instead of a rubber bushing. I've run this roller type idler arm since the 70's and it is still good.

Both of the things you mentioned are in fact inherent problems with the '67 down design. A cantilevered beam design is an inherently weaker design, its engineering 101. That is not to say they can't be used or that they're dangerous, but in this case the '68+ version is a better design.

And sourcing the idler arm is a problem too. The '67 only version is expensive, and if the quality of the reproduction arms has dropped then the steering will suffer.
