for the different size shields, you will have to dig a little.

you want orifice 10mm. Make sure it works for a 300sdl or 86-87 300d just to be safe.

By googling, I found a couple of suppliers.

Thanks for all of the help. I work long hours the next few days, but should have the results of some paint or machinist's dye on the nozzle Sunday night.
If there are any other suggestions, I'm willing to try most anything.
