The cap should retain the insert but in your case might not have. If the insert is not damaged and still has a smooth intact babbitt without cracks, crazing or other damage they may be okay to reuse. FYI: The rods have babbitt poured directly on the metal surface without a metal backing. How Sweet the roar of a Chevy four!
