This stand-off will have to be moved towards the center tunnel.
By the way, the factory 914-6 GT cars used an 8mm HEX nut as the 'stand-off' shown welded to the crossmember.
This photo actually shows a round threaded piece we fabricated before finding out about the hex nut detail. Of course, we will be changing this part to the factory hex nut as used by the GT.
