Windage tray fitting, what size bolts?

[phazed]

When I bought my baffled sump last year I ordered the additional Windage tray that bolts to the bottom of the block inside the sump.

As I have the engine apart I thought I might as well fit this.

There are 10 tapped holes in the bottom of the engine block, does anyone know what size thread these are?

Don't know the size but as they are into the ali block they will be UNC.
All you now need do is measure the size.

Try a sump bolt for size if it fits its 5/16 UNC if not it can only be 3/8 UNC (unlikely) same size as the exhaust manifold engine mounts etc Peter
