73 Dart 4 door leaf spring bushing size?

Hello! I recently acquired a 73 dart with the 225.
It came with a shackle lift for the rear, and I’m sure that I will need to replace the bushings when I install it in the springtime.

What is the correct size bushing I need? Do 4 doors having different bushings than 2 doors?

I’m new to A bodies, and this forum seemed like the perfect place to ask some questions!
