I've went to the auto store and hardware stores looking at different bushings and nothing will fit. Hopefully someone can help me because I have no Idea what to do next ???

Thanks for any help,

I believe what you have is a head with a straight cut thread and your new bushing is a pipe thread (NPT) which is a tapered thread, they won't work together. One solution is to retap the head to the new bushing size.
