Hot to check clutch disengagement measurement with blow proof bellhousing

Thanks for the input guys, i have a feeler gauge set, going to se if i can rig up a tool to snake in there. Also on the note of the blow proof bell housing, my dad is actually the one one who bought it for me, he would absolutely not let me run the aluminum bell. Housing. I thank him for looking out for me.

You dad is on the money. If you ever see what happens when one lets loose you'd never run anything else.

But at the moment I am violating my own rule and using an OE bell.
