Frets on the net have been very good to me also I know the sinclair gets flack but I think its a great bridge I buy all that I see online so I have spare parts but never seem to get the bars....
I made my own bar in our factory workshop out of a 6.0 mm stainless steel rod.
Bend according to your needs.
I took the trem bar of my Steinberger Spirit as a sample.
