Clutch Dimensions Please





I'm attempting to swap a Gen V LT1 (actually an L86) in place of my Gen II LT-1 in my carted out C4. I'm attempting to keep my ZF6-40 transmission and I've taken a bunch of measurements of the flange and input shaft spacing to try to figure this out. My current thought is that I can use a universal hydraulic throw-out bearing with the 8 bolt flywheel and clutch assembly from the Gen V, but I need to know the thickness of the flywheel and clutch together to determine if there is space for the throw-out bearing, and if so, how much space. Here is my hand drawing of how things would line up and it should be accurate to within about 1mm.
I appreciate any help!
If you want to see my little YouTube video of me taking most of these measurements in case it helps answer any questions, here it is:
