[Heathkit] Red Grommets for early Heathkit Test Equipment

[Joseph Devonshire]

I'm working on some early Heathkit test equipment.  They used Red grommets on the feed through's for the test leads.  I'm trying to keep the appearance as original as possible. The opening is 3/8th inch, and I need the grommet opening to be at least 1/8th inch.  
Does anyone have a favorite vendor to get these from?
Thanks, and 73,Joe  AB1YO
