Radiator bottle 1985 cucv blazer

Hi Guys ,
I brought my first Cucv ,Always wanted one since Desert Storm (New Zealand) where my unit stole one for job.I now live in California.
I need a few items and I have already brought a couple from hillbilly spares ,but i need a expansion radiator bottle ? can you still buy them new
thanks

They make a new one from NAPA. Not exact but pretty near as close as you are going to get. I can look up the number in the AM. If you want.

thanks Guys
