Counterbalance spring assembly consisting of 4 Torana suspension springs. The difficulty of precompressing the springs was overcome by building a ratcheting compression mechanism into the assembly.
Built a slider mechanism to convert the donor car wiper motor into a normal cobra push-pull assembly. The throw is adjustable to obtain the correct wiper angle.
I did this because:
1.Commodore replacement motor will be easyto get in future
2.Plugs easily into the harness giving full functionality
3.Cheap - came with the donor car!
