Would someone be able to identify the head bolt size (mm & thread pitch, etc.). I used the thread identifier at the local hardware store and neither the SAE or the Metric appeared to be a perfect match. The threads on the existing bolts are in good shape. Thank you.

Thank you. The M10 x 1.25 pitch on the thread identifier was the only one it would thread into but was sloppy loose.
Thanks again.

Do you need head bolts?
