Hello, sorry yes. The door handle mechanism is the same on a mk1, mk2 Golf, mk1 Caddy, Mk1, 2, 3 Polo, Mk1,2 Jetta. the grommet/ gasket you need will fit from that kit.
If you want "Delocked" handles (handles with no locks in them) then look for rear door handles, again they're exactly the same minus the keyhole, etc and fit straight in. You will need central locking/ another entry method though of course
