What size bolts do I need for mounting flex plate to the crank on my 360?

Thank you.
 
They are shallow headed bolts for clearance and the head size is either 3/4 or 5/8,can't remember

Go to Jegs or Summit and buy a set of ARP. They will be correct.

that link shows FlyWheel bolts for a manual trans. I like the idea that they are longer than flexplate bolts so a flexplate spacer isn't a problem when using a mid plate. But i have 2 questions.

is that the part# you bought? Flywheel bolt heads/shanks work with the flexplate and spacer or is that just a random one you posted from Summit's site? did the shank under the head clear the shim and flexplate?

Did you have overhang through the crank that had to be shortened? (were those flywheel bolts actually too long by a little bit?)

I am pretty sure I have a set of stock ones.
Message me if interested.
 
I forgot which. They're either 7/16-20 fine thread or 1/2-20 fine thread.
