Lexus IS250 - Replacement Windscreen Washer Jets - Alternate Type?

[Quince99]

My IS250 (2006) has an extremely reluctant windscreen washer jet on the driver's side. The passenger side has two jets in a V-shaped arc that seem to be vaguely effective whilst the driver's side has a single stream that doesn't hit the centre of its intended area. I've had the jets off, flushed them with water, agitated and removed a small amount of debris and attempted to re-align the jet with a pin and cocktail stick! I've also checked water flow from the tubes and that seems consistent on both sides.

I'm probably looking at replacing them with new versions of the same type but is there a washer jet from a later model IS that fits but has a different spray pattern, does anyone know? There is pretty much nothing on eBay and the one IS for breaking that I saw had already had the washer jets removed!
