What size headlight brakets?

[YouFancy77]

So I have a 89 gs500e and I bought a pair of 37mm headlight brackets for it the other day and they didnt fit my forks.  I measured them and they are 37mm, has this happened to anyone else?  Anyone have any suggestions for aftermarket headlight brackets that they have used that fit?

I used these and they worked great.  Allowed me to fit a 5-3/4" Headlight securely.

Here is a photo.  Not a great view but if you can zoom in you should be able to see it.
