Radiator Overflow tank

Radiator Overflow tank
I want to install a tank on my 1971 Cutlass w/350 engine. An original spec is about 180.00. I found the wandering the internet. Any thoughts, or experience of any that would fit reasonably well. At the price I'm tempted to try one. We owned a '78 Firebird & if memory serves the right inner wheel covering is similar to the Cutlass.

I installed a Dorman tank from the local auto parts store and it works well, so that one should be fine. I'm a functionality guy as my car is a daily driver, though, so I'm not so concerned with originality. Then again, I thought the overflow tanks were first offered as a dealer installed option starting in 1972.

It honestly looks good to me. It is a lot better, although more expensive, than what I am using.
I have been thinking about getting a larger reservoir. I have a ZingZang Bloody Mary Mix bottle that should do the trick.

On my 1982 delta 88, the original rad expansion over flow tank is mounted on the fender well . That is a bad location to have it , as its cracked and pushed in from shop workers leaning on it . The pushed in cracked top of the coolant tank collects dust and dirt and directs this dirt / dust into the tank . Then what ! dirt finds its way into the engine and water pump seal . So no point in buying a new original tank as it will just get leaned on again and crack again . So i also use a glass whiskey bottle mounted on the passenger side . It does take a while to figure out the proper level of coolant . It will take some thinking of how to keep dust and dirt out . Could cut a finger off a disposable latex glove or cut a used rubber bicycle tube , pull that over the glass bottle .
