shackle bushings

[72 340 4spd AC]

Looking for the part number for the rear shackle bushings that go into the P4452984 / 5 leaf springs.

The Moog K7309 is to small ID inside the spring.

Thanks in advance for any help!

I bought mine from PST, but I don’t remember the part number, it’s been a while.

Hey, thanks a ton! I ordered the Moogs
Apparently Rockauto site is incorrect, consequently I have a set of K7309's if anyone wants them.

Do you know if the Dayton HB889 are rubber or if any of the others are rubber similar to OEM
The Moog K7308 are made of Hard plastic and the ones I removed are rubber

All of the listed numbers are rubber, or should be. Although Moog quality has been declining for years, the K7308 should be rubber as well, unless something has changed even more recently, or perhaps the plastic (urethane?) bushings are mispacked, or were substituted by someone.
