I wouldnt worry about it if it is tiny. Try and find some black 2 pack epoxy adhesive and put some in the crack. It will be years before it gets any worse.
Nearly all the US californian 240Zs come with cracked dashes.
Buying a full dash cap from the US and fitting it PROPERLY does make a very good job and not detectable to the average viewer.. IMO
well, ill keep an eye on the crack but i was so happy i had an uncracked one and now i discovered this while cleaning it
maybe that dash cap is interesting, cause i dont want a piece of carpet lying on my dash to hide cracks..
As Pete says, but when you apply the epoxy you will have a few mins until it sets, when it is tacky get some blue tack or putty, press it onto an uncracked area, this will leave a dimple impression on the putty, use that to then dimple the epoxy, then when dry you can colour it......worked a treat and is much much cheaper than buying dashboard repair kits from Halfrauds
But I can advise you that very shortly, there will be a european supply of complete f/g dashboards !
Remove your cracked (and heavy) item and replace with a complete unit, ready to cut out (gauge, ventilation and glove-box) holes as the owner requires.
Mounting as per the original unit OR using a lightweight frame behind.
I'd imagine that they'll be less expensive than a dash-cap once postage and (in unlucky cases) customs have been paid.
"But will they be the same shape/style/look etc as an original? If so, would probably be interested!"
Absolutely no point doing them otherwise my friend. In fact for techincal/production reasons, they need to made smooth (which some may like) - I invite you to look at the two photos and video :
Yep. Sprayed it in the kitchen. Got everywhere - covered the surfaces & floor, and filled every nook and cranny!
Absolute nightmare to clean up I tell you!!
And yeah, it's progressing (!) well, just annoying the wife tried to fix it first, and after ruining it I've had to strip it bare and start rubbing and filling it all over again!
