Identify factory sway bar piece?

The 73 and later sway bar is shorter , fatter , lesss bend. The early bar went around the K. Long skinny pissy looking bar for sure. Even though the later bar has less bend it still required a fairly large odd shaped hole through the K so it comeuld thread through and out the other side.
Please note, If you already have the later model bar, even a weak bar is better than no bar. It will thread around the later model K member but it also used triangle shaped brackets low under the front. They would get bent or get their bolt ears broken off.
The through the K bar held its mounts up higher, between the legs of the K. Entire bar out of harms way.
Optimum combo in my opinion, Sway bar around the K, but with smaller square forward mounts ( Addco ), and rack and pinion steering through the K.
