UPC toilet top lever

[charger]

I have a one piece toilet with a top lever. The chrome lever broke and I am unable to find the part to replace it.
The toilet has UPC at the back of the toilet seat. The tank cover has these numbers written inside:
Made in U.S.A. - 4025; 4026; MJAN229375
I tried Crane but I was not able to locate a flush lever that operates from the top of the tank cover.
Any help would be appreciated.

UPC means that Uniform Plumbing Code deems it compliant to their standards.

4025 4026 is American Standard i believe it was a "Compact" toilet.
The replacement trip lever for it is a model number 047148-0020A Chrome.
You should be able to get a fit's all handle from the big box store, Fluidmaster has one it's part nuumber 681c that will bend in lots of different directions.
