Egr Bolt Size

Hi Guys, does anyone know what size the bolt heads are on the EGR valve on an 87 lg4?

such a tight little space to get into and i no spanner (spose theyre wrenches in the states) seem to fit it tightly enough to get a hold on them.

any tips for removing this little sucker?

If 8mm is close but not quite right, try 5/16"
