I rounded up a nominally sized 16mm stock rear sway bar and I'm trying to determine what size bushing to use. I'm thinking it came from a '68. However, the bushing locations for the chassis mount and the drop link have a unique shape to them - they're not flat and are reduce in size to around 15mm+. This is a first for me. I've already ordered 16mm bushings, but now I think they may be oversized.

1 - Has anyone seen a bar like that?
2 - Could the age and wear have reduced the size (don't think so as the paint is shiney there)

I'm attaching a crude, exaggerated pdf to illustrate the shape (better than a photo as it's pretty subtle).

thanks,
