Default Clunk from the rear under hard acceleration

Looking to get some pointers or guidance before I put the car in the air....


I have a 2001 trans am, m6, stock rear end with koni shocks, bmr springs, lca, lca relocation brackets, Panhard, and sway bar. I had the transmission rebuilt recently as well, and haven't put very many miles on it since then.

Under hard acceleration, standing or rolling, I will get a clunk from the rear end. Doesn't happen every time, but once is enough. Is there anything specific I should be looking? Thanks

My car would do the same, ended up being a cracked factory torque arm.
