1983 rm250 radiator used on multiple years?
 

I recently picked up an almost completely destroyed 1983 rm250. Restoration is an on-going nightmare haha.
Both radiators are pretty much destroyed. I started looking at OEM sites for replacements and quickly found no one had them.
I managed to grab one off eBay, but that still leaves me with one more....

Does anyone know if the radiators that were installed on the 1983 rm250 were used in later years as well?

--Bonus question. Are there any years that are interchangeable with '83 radiators?

Thank you!
