Welcome to the forum.

Sounds like your missing most of the parts. No worries though as the entire lower end is available new.

A replacement piston/cylinder would be a #4 cylinder. This had two bypass ports and two boost ports, one one each side of the bypass port, for a total of Four.

These are hard to find new. A suitable replacement is this:

If you need a needle, needle body and venturi they are also available new.

Can also search eBay for parts lots but it can be hit and miss on usability of parts.

An entire used TD in good condition can also be found on eBay. Can use the parts you have as spares.

There are options to get you up and running again depending on budget.
