Airbox bracket engine spacer / collar

[parfy21]

Hi,

Does anyone know the size / specs / source for these spacers / collars that sit atop the engine around the bolts for the airbox (plenum?) brackets. They are present on one back but not the other. Im assuming someone lost them along the way, but if anyone knows that they shouldn't be there let me know!

Hi Parfy

They are EVERYWHERE on t'Web

Sorry about PH's reorientation
