Rollbar stay mounts

[skov]

I think someone told me that the standard CP9 chassis plates that the rollbar stays mount to fail the IVA as they only have one bolt each and need two.
Anyone know if that's correct?
If so, what are people doing about mating the rollbar stays to the chassis?
Is it ok to keep them in the same place, but make them wider with two holes, one either side of the stay?
