Any ideas on Radiator? #2898054

Long story..lol. Going to tear it apart and replace cam in 383 h code. Looking at radiator and trying to locate a new lower hose to replace when I put it all back together, I started searching for the part number(s) listed on top of radiator. Every radiator guide and spec sheet I found here and other place skipped right over the number. Any ideas?

The car is a 69 charger and I haven't had any overheating issues. It does have an aftermarket overflow tank added..

383 bb 4 bl
Radiator no? 2898054

Dimensions. (Core area)

I added a pic of numbers to hopefully help..

Thanks!
