420A Dowel pins block to head

[DSM-kiezerz]

Anybody know where I can get a set of 420A head dowel pins P/N 4448856 I just rebuilt my head and found out one of my dowel pins was broken Now I’m stuck trying to find a replacement I tried looking everywhere autozone, advanced auto parts and O’Reillys and even the Chrysler dealership they don’t have them. If anyone knows where to buy one or has a pair let me know thanks

What is the OD of the 420a dowel? Do you have a pair of calipers or micrometer to get that measurement?
