ZL2 Hood Grommet

[Z28Project]

I was looking at the available repop hood grommets that the solenoid wire goes through, and they are nothing like I remember them being back in the day.  They just have a big hole in the middle.

Did GM change to that style at some point later on? 

Does anyone make the original style or know any availability of originals?

Here's the repopped grommet that everybody carries:





It is nothing like the original grommet that came with this hood back in the day:








There seems to be very little information or pictures of the original style grommet.   Just wondering why the grommet was reproduced so inaccurately??

Back in 1969 that grommet was probably a common off the shelf [COTS] part supplied by McMaster-Carr or the like. It's known as a 'witches hat' grommet because it was molded closed; the tip was trimmed to match the size of the wire.

What they now sell is as close as it gets; I doubt that's a reproduction. Even if you could find the original style there is probably a big minimum buy.

Hmm, this looks like a perfect item for me to protoype a correct molding.  I wonder what the demand would be?  But at $8 a re-pop, it would be tough to recoup my time put in. I have not done a molding project since I did the RS washer valve plastic part.

The retaining prongs are part of a steel stamping so that part would also have to be duplicated. The rubber was molded over it. Rubber doesn't bond to untreated steel; rust is visible in the photo of the original. They didn't hold up very well.

The ZL2 grommet is similar to the speedo cable grommet [3792008]. The steel part may be the same; maybe you could obtain a supply of those and strip off the rubber. My guess, the part sold today is the speedo cable grommet.

I can't see real well with my console gauges in place but it sort of looks like the factory shift cable grommet. The replacement cables come with a flange seal...Joe

Do it!  I'll be first in line for it!  With everyone striving for accuracy I'm surprised this hasn't been addressed.
