I’m the middle of doing a frame off rest and when I went to remove the steering pump I realize the top has a hole on it (looks like a bolt goes there) and you can hear it slush inside when you turn the knuckle. Can anyone tell me if I’m missing a cap there? Car came like that. Also frame is off and not too bad , still bad enough that I will be sending to sandblast and Powdercoat. But the under carriage is in real good shape imo. Is there anything that will stick to the Chevy wax coating? I’d hate to see a new frame and see the underside look old, but I feel like chevys coating still has a lot of life left. Maybe pressure wash and apply something? Tia
