Graflex Super Graphic

I have a Super Graphic with the Graphlex 135mm Optar lens. One of the bi-posts for the flash cord broke off. Is this repairable? Would it be better to just replace the lens, I see them on the auction site for $50-$75.

Replace the shutter.

The Bi Post pins screw onto the shutter via a screw post inside the shutter which secures one of the contacts for the flash sync. A fair amount of disassembly is needed to replace the screw post and pin if you can find the part. The pin is standard but the screw post in the shutter is specific to the position on the shutter.
Download the Graphex Shutter Service Manual here: http://www.southbristolviews.com/pics/Graphic/manual-pdf/GraphexShutterService.pdf and take a look at pdf page 20, items 4 and 5 called prong and prong screw are what you need.
