Heim Spacers for Bilstein Shocks?

[JonsGottaDusta]

Hello Everyone,

I got these shocks from a friend that used to work at Bilstein and they were custom tuned for my '71 Duster. I'm finally getting around to hacking up the front suspension and due to the metric size of the heims, I cannot seem to locate any spacers to work with on the mock up. Looking to get into something near a 7/16" bolt and I'll need 16 total. Does anybody have any thoughts or ideas on where I can locate such a thing?

thanks,
jon
