I got a couple of those backward hangers!!!!!!!!!!! I didn't know what the heck was going on and pulled, and pushed and shoved and finally gave up.
I took all my hangers and dropped em into acid bath.... removed the zinc and clear coated them. They've maintained a nice natural finish.
Bright plated is to me, like having bright plated body bolts.
That's just me.
If you are restoring it's your choice. There's a lot of Gardner exhausts out there. When I talked to him, and asked about the plating, he said 'buyers prefer them that way'... so style and fit are correct but the plating is not.
