LCA sway bar tab question

I am adding a factory sway bar to a 72 Swinger just wondering if its worth switching lower control arm to one that has the sway bar tabs or should i modify original to accept bar? also are 72 lca with sway bar tabs the same as 73 and up or is the mounting location different?

67-72 LCA tab locations, sway bar, and K-members are different than 73-76 LCA tab locations, sway bar, and K-members.

The 67-72 has a wider sway bar that mount in front of the k-member. The 73-76 sway bar is narrower and goes through a hole in the k-member.

There is no hole in the 67-72 k-member to take a 73-76 sway bar through it.

Here's the difference in LCA's
