Lens cap for 17-28mm fisheye

I lost the push-on (aka fall-off) cap for my 17-28mm fisheye lens. Does anyone know of a suitable replacement?

The cap on my F17-28 says 51mm. I do not know if this is an exact fit but it is 51mm.

I tried my F17-28 lens cap on few of my 49mm filter diameter lenses and the cap did ft. It was a bit loose but it fit. I know you typically order an external cap 2mm larger than the filter diameter so a 51mm push on cap appears to be correct.
