Where to buy lever for Toto toilet?

[NullPointerException]

We have a Toto toilet. Recently, while adjusting something else, I managed to snap off the end of the lever at the point where the hole is that the chain goes through. Until I get a new lever, I've duct taped the chain to the lever. Duct tape saves the day again.

I've tried several levers from the orange and blue boxes with no success. From looking online, it appears I have to buy a special lever and handle that is compatible with my type of Toto toilet.

Here is a link to a picture of the inside of the tank:

I'm wondering what type of Toto I have and where I can buy a replacement lever. I didn't see any model names on the toilet anywhere. It says "Toto" and "1.6 Gpf" as you can see in the picture. I've seen some Toto levers online, but I'm not sure if they are the right type. I was surprised at how expensive they were in some cases (up to $80).

Thanks.

It's looks like a Toto Ultimate, MS854114 from some years ago.

Lowes Hardware will sell a replacement fill valve, the Korky Quietfill, and the repair part for it.
and the blue 3" flappers when you need a replacement.

Any standard side mount trip lever should work for it, I believe the Eljer might work there.

The book price on a chrome THU004#CP Toto lever is $23.00

Thanks for your help.

Last night I happened to be at my local privately run hardware store to pick up something else. In the plumbing section, they had an Eljer side mount lever that looked like it would work. Took it home and installed it. It was about 1/2 inch too long, but after cutting the end off with a hacksaw it worked great.
