Thanks - that's actually a good simple form of insurance and would be fine in a racecar (wish I'd come up with it myself - doh!). Would obviously need to create space/holes for the bolt heads.

i installed it into my1k and didnt have to make any extra mods other than a hole through the mount.

You have to take the mount out, and pull it apart, and work the bolt into where you drill the hole. its a pain, but the cheapest insurance you can find. You dont even have to use a high tensile since there is no side loading of the bolt, but it wouldnt hurt to use one.

I had to trim the head of the bolt a little since I put it reallt close to the standard studs and it got in the way.

When ou do it, just sit down for 5 mins and look at it and it will all make sense.
