Does anyone have the lengths of alloy head (67-1126) A10, 58-59 Super Rocket, headbolts to hand please?
Have a BSA service sheet with iron head lengths, but alloy ones definitely differ.
Also I have managed to screw a thread insert too far into the barrel in an attempt to clean up a sticking thread with a tap. I may be able to deliberately screw the insert further in and fit a second insert, but is there a trick or tool to remove an insert without damage?
cheers
Mike
