G'day Rick,

Try contacting Tony Mamo, I vaguely remember him mentioning recently on here somewhere that he has a version of the Yella Terra ultralite that uses an M10 bolt, hopefully this helps.

Best wishes,

Jason.

He's normally an active member on here although not too much in recent times, there's plenty of posts of his throughout this site with his contact details. You can reach him at Air Flow Research cylinder heads, extn 109 or PM him. Really knows his LS stuff, honest, solid and helpful guy to deal with.

Best wishes,

Jason.

One option, not sure how much it would cost, is to use a keensert or timesert. Only issue might be the 10mm might be too small for an insert. I believe you can get the keensert in an M8-1.25 internal thread but the external thread is M12. Might be another option to look into.

Also, have you explored punching out the bolt diameter of the stock rockers so an M10 will clear? You may need to use an allen bolt or something with a smaller head.

Why not pick up another set of the rockers like the ones that you sold?

I sell the M10 Yella Terra Pro......is this a hyd roller or solid?

If its hyd roller I would opt for the non adjustable version which has a lighter rocker arm.....just a beefier version of the common 6645 rockers essentially.

PM me and we can go from there!

Cheers,
Tony
