Type 4 undertin bolts size and pitch

Searched everywhere can't find - anyone know the correct size details pit h to fit genuine type 4 undertrays to the engine case?

 

M6 tinware screws just like all the others.

 

Are type 1s different to type 4s? The ones for my type 1s don't seem to fit?

 

Are your case threads knackered? Always good to run a tap up them.

 

Will do
