Hi Phil

Any chance you could give some detail on the bolts as I have recently aquired a pulley but no bolts.

Thanks Ian

They should be the same as the stock pulley boss for the stock crank pulley, maybe a hair longer. They should be M6 I think, 1.25 pitch. Make sure you get some quality grade 8 bolts though. I had issues with the stock crank pulley one timing belt change... kept over torquing, and they would sheer....

If you can get one out, most bolt places will have replacements.....

Dave,
