Source for rocker shaft end seals/freeze plugs

I spoke to Chrysler and they are not producing the rocker shaft pressed end seals/freeze plugs. They have not said that they will again.

Spoke with Mancini Racing. They have been out of stock for 8 months to a year.

No one has stock left anywhere

I found a dorman part that might fit. Anyone used these before?

Dorman 555-007
