Description
Installs on the outside manifold studs.
2 required per Metro.
This is not an off the shelf brass nut; it's the original height of an original.
The nut is also original for the manifold clamp (5/16" Fine Thread) if you want to keep the original look. So if buying one of our clamps you may have to switch one of the bolts to a fine thread since they usually come in Metric.
