I would presume pressure is against the main thick body so that there isn't force to push the grommet mushroom out.

It mounts from behind/beneath the tunnel and the round protrusion passes through the hole into the cockpit. My Mk3s don't have them, replaced by a welded tube in the tunnel, but I looked into it wondering what the difference was between the Mk1/2 and 3, etc.

BTW, Brian, nice job on the part!



Best,

Paul

Thanks Paul, Your cars are like my GT6, welded tube inside the tunnel. So this grommet must have been on the very early Spitfires. Well, it's another previously NLA part brought back to life. I'll add this to my catalog.

Yes, Brian, I think you have it right. This specific piece was off of the black car and Dorothy never had it and the handbrake wasn't functioning when I bought it, so I've never operated the assembly.

Okay, the hole is about 15.5mm, but it's not exactly round anymore, so it varies +/- 1mm.
The metal is 20ga, so 0.036 or so thick. I'm a bit thicker because I put raptor liner on the underside.

Thanks,
Chris

Ok Chris, I'm going to make an adjustment on my dimensions since I had guessed at the hole in the car body being 1/2" , I'll bump that up to around 15.5mm or .610 and then print some samples to send off to you. I'll PM you when they are ready so I can ship them to you. Just be looking for your mailing address.

Ah, crap, I forgot to measure the cable. It's the standard handbrake cable...not sure if you have your's handy, but it should be the same. As for the hole, I think the outer diameter of the rubber is only about 16.2mm...you think 15.5 may be too big? I don't think the thing has to fit too tightly in there, but I'm afraid only a mm or so may be asking for it to slip back through. I defer to your judgement, of course.

Thanks, Brian.

yes, that doesn't leave a lot for the rim. Seems the 15.5 is a little big. I did make the mushroom slightly larger but is may or may not be good enough. It's on the printer now but what I'll do is sent all the ones I've printed down to you and try fitting them. Then you can make a judgment from there as to what one fits good, and if we need make an adjustment we can.

I used the dimension you measured for the cable hole but allowed that there is some wear. Lets see how these example fit and go from there.
