Does anybody know where, on gods green earth, I can track down mounting brackets for my '40 Series 60 (or 70 I think and maybe even a '39's) running boards. I have 1 for the rear pass. side but will take the set if it's sold that way

 

Have you tried contacting Summit Racing on their website? A couple of the reps were able to steer us in the right direction for some specialty parts when I couldn't find them anywhere else.

Also, if you haven't already checked, try craigslist. see if anyone is parting out their old rig and you might be able to get something that matches up.

We're still trying to find just a set of running boards for our Series 60 (building on a tight budget doesn't always work so well). I might just end up fabricating something here at work...

Anywho, good luck. I hope you'll get some help with your search!
