Got a weird one. Clicking that occurs with engine speed and suspension load.

I have never seen anything like this, it's like I'm a weird problem magnet. I have an 85 corvette with the 4+3 manual transmission and it's making an heck of a racket. It's a loud click and rattle that happens when cold and increases with engine speed, but ONLY when the suspension is loaded.
Get out of the car and it stops, sit down and it starts clicking. Bounce on the suspension and it goes from quiet to clicking every time you land and compress the suspension. It also stops when the clutch is depressed. Obviously it's something in the transmission, but what? The bellhousing bolts are tight, as are the trans to bellhousing bolts, it's not the TOB, pilot bearing, or clutch fork.
The transmission and OD unit function as they should, just this weird noise, and it does go completely away once the car warms up. Any ideas?

Broken engine mount?
edit: I'd also look at the pulleys mostly the tensioner. Also I am assuming your not talking bout valvetrain IE rockers

Sounds is coming from behind the drivers wheel well, which would be in the flywheel area. It's a new flywheel on there, but anything is possible. I can look at the motor mounts as well. It's not in the serpentine system, I already tried it with the belt off and it's still making the noise. Definitely not in the engine, not the valvetrain or lower end.

jack, support with plenty of redundancy, remove the inspection plate (do manuals have these?) and check for loose bolts. ive head they can back out and might be striking something.
you r getting close.

Make sure C-Beam bolts are torqued correctly and verify there are no cracks at either the trans tail shaft housing or the diff housing where the C-Beam bolts pass through.
