![Question](https://www.rx8club.com/images/icons/icon5.gif)
Okay so before I replace my engine mounts with the new poly ones I made the other day I wan't to change all the nuts and bolts with new ones as a snapped bolt was what ruined my current poly mounts.
I did some searching and found that the top bolt is M10 with a 1.25 pitch, 30mm length and thats ordered.
But I can't seem to find anywhere what the nut and the bolt that goes into the frame is? Anyone know?

What i've assumed is since the top bolt is m10 x 1.25 and 30mm long, the bolt that goes into the chassis looked the same to me but shorter so I ordered a m10 x 1.25 and 20mm long. And I ordered a m10 x 1.25 nut. I am pretty sure these will fit, i'll post back once i've done it with my findings.

Okay I just did my engine mounts, the nuts and bolts for future reference are:
Top Bolt: M10 x 1.25 (30mm)
Side Bolt: M10 x 1.25 (20mm)
Side Nut: M10 x 1.25
The stock nuts/bolts require a 14mm socket.
The new nuts/bolts I bought require a 17mm socket.
With stiffer mounts comes greater vibration. I used threadlocker blue on all of them.
Installation was a success!
