Thanks for all that.
How you figure to prep these? If I were to do it today alcohol & nylon brush. I have some 99% but that might be a risk, I'd probably use the 70% & a rinse. Shame I have to paint the NOS Custom/10, I'd slap that on today but it won't match the rest.
I have a few "NOS" syringes & may give them a try. Think I'll pull the trigger on replacement 400's. Just for curious, and some day they'll be NOS too

They appear very close.
I wonder how close replacement Custom/10ish badges are?
Check it out Tim, reads "perfect for auto. trim" even
