Hi I need some help. I have managed to damage one of the bolts that hold the motor mounts to the block. So now I need the dimensions and thread size of those bolts. The bolt is still installed so I can't measure it so I hope someone here can help

 

M12x1.25

I used 35mm for mine with the oil pan brace. I would imagine that about 25-30mm is what you would need for stock (without an oil pan brace).
