Exhaust manifold bolts holden V8

Hi everyone,

I need to get a hold of some bolts to bolt the extractors to the Holden V8 engine thats going into my LX, can anyone tell me what size/type they are? and where I might be able to buy them from?

OR If anyone has a complete set they'd like to sell me or even one i could borrow to identify them with the local bolt shop?

Cheers Pete

Not sure if ithe commodore 308's etc were metric etc so maybe you should post whether your motor is a red,blue,black, vn 5 ltr etc too.
I am pretty sure you should be able to get them from an auto shop or straight from holden.

Its a red 253 from a VB commodore
