NC 1 2.0 sport rear coil spring rubber top mounts - unobtainable? - use front instead?

Hi,
As we are unable to take our cars out much at the moment i decided to fit a set of Mazda speed springs that i had. The front went well and i replaced the top spring rubbers / dust cover which didn’t really need replacing. However when i have got to the back the rear ones are not in good condition and are torn, however unfortunately i haven’t been able to source any replacements new or used from MAZDA, MX5 parts / Autolink / MX5 heaven etc so i was considering cutting down the dust cover part of the spare front ones i have just removed. They appear to the same dimensions (apart from the length of the dust cover) and made of the same material.
Does anyone know where i can buy the mounts from via the internet, or if i have to can i reuse the front ones on the rear.

Many Thanks
Jason

Got mine from mx5 parts last month… Had to wait 6 months for them…looks like they did not order many…

Thanks, i have tried them but they aren’t getting deliveries from Mazda

Now in a similar boat in late May. Did you use cut down front ones?
