Now that we have established that some 69s they installed a "L" bracket late in production and screwed it to the 69 battery apron what is the Judging guidelines for these brackets? Were they only used on group 27 cars? Was there a service bulletin where earlier group 27 cars would have been fitted with the L bracket when in service? Installed before sold(if unsold when the bracket started being used)? So is a GT500 or a GT350 with the group 27 deemed concours acceptable to have that L bracket screwed to the 69 Apron regardless of when the car was produced? Thanks. Gary
