WTB Williams 1960's lockbar endcaps

[DRANO]

I know these are hard to come by, but I'm praying someone out there has a great horde of parts or is parting out a similar era pin ad is willing to help me out.
This is for my recently acquired 1964 Williams Heat Wave. It's an awesome game and I just spent a few days cleaning it up.

Here are a few pics.
















I think the game turned out really nice... but, as you can see in the pics, the right side corner cap is missing. This is the last thing I need to make this a super nice example.
I've found one place with an entire bar in the US, but they want some pretty hefty coin for beat up examples.

Please shoot me a PM if you have any leads.

thanks!
