Front chassis replacement on a ls1 4th gen?
I am in the process of doing that now. Find a good donor car and drill all of the spot welds out and remove. Reinstall in reverse order.
Time consuming but not hard to do.
Tools needed are still, spot weld cutter, welder and maybe some means to pull anything that may be out of square back straight. Like a port-a-power or come-a-long.
