Had a coolant leak from the intake manifold that turned out to be the spout had corroded away more than 50%. Tried to find the gear to tap in a fitting, but had no luck.
After a false start at a mechanics shop, I went to 'Head Exchange' just near work.
They turned up two replacement fittings and ally welded them in place, and cleaned up the intake manifold.
When picking up the manifold, I got a walk through the shop....
They have spare F5A, G10, think even F8B heads on the shelf, and a great and open approach to odd requests too!
Just sharing the good experience...
