I have an 87 305 formula and the radiator tank on the driver side cracked.

I called to get pricing for tank repair and its 90 bucks or up.
O'Riley sells one for 120 and auto zone for 90. This is the whole radiator not the tanks.

Question is has anyone bought from either place and what were the results of cooling capibilities.

 

They should work just fine the only thing that really matters is longevity, Just get a cheap one with a lifetime warranty.
