Header bolt size?

[Stephen@NCAutoUSA]

I've checked a lot of places but can't seem to find the right size. I know it's a 8mm but is it 1.25 or 1.5?

Thanks

The headers are held on by nuts over studs, as opposed to bolts. I do not know the sizes, unfortunately.

Helms is your friend page 9-3 and 9-4

Header nuts to hold the header to the head: 8x1.25mm
Nuts that connect the manifold to the downpipe/muffler: 10x1.25mm

Enjoy!
