Replace 1992 Crane tank

My toilet tank cracked recently and I'm haveing trouble finding replacement information. It's dated 1992 and has "1621" on it which I assume is a part number.


Anyone have advice on how to track down a compatible tank?

thanks

If I'm not mistaken, that is a 3.5 gallon tank which isnt manufactured anymore.

Excellent time to switch over to a Toto -- that's what I'd do if I were in that situation...
