Anyone know the Size of the 3 screws to fit ACV block off plate?

Hey all,
Searched and couldn't find anything, I bought a pineapple racing block off plate for the ACV but it did not come with shorter screws, so right now I have it held on by 8 washers on the screws and 6 on the stud, and it is also leaking i believe. I am curious if anyone who has installed one found the correct screw size and pitch and remembers what it is, so I can pick up the correct ones?

Thanks,
David

If your original bolts have a 10mm head, they're M6 x 1.0.
If they have a 12mm head, they're M8 x 1.25.

Those two sizes account for about 90% of the hardware in the whole car.

Three oil pan bolts can work, unless the block off plate is too thick, in which case never mind.

Just to update anyone, They are indeed m6 x 1.0. I cant remember what length I got but slightly longer than 10mm with locking washers(Don't know if I needed them or not but I got them anyways) Also made a gasket out of a cut your own gasket sheet, paper/rubber mix and everything appears to be sealed up good now. Bolts fit great also.

Thanks!!
