Hardtop fixing bolts

[phil.dobson@mac.com]

Can anyone advise the size of the chrome bolts that secure the hardtop just behind the seats. (the main fixing points). I have just received two from SNG but they are 1 size under the bracket fixing thread. It looks form my research that the V12 is the same size so not sure why I have this issue?
Any help appreciated.
Best regards

Is it possible that yours have been stripped and drilled out to the next size?

I don't have my roadster handy to measure.

It must be a possibility but it’s not happened in my ownership (30 years)

Just to close this out, I removed the plates and on viewing the threads from the rear it was obvious that they had been interfered with at some point. The plates have now been replaced.
Thanks for your help
Best regards and stay safe.
