340 Forged Crank Dampers Interchangeable

The 68-69 340 balancer is the same balancer as the 67-69 273 and 318 FYI. Or rather same part number. A few years back, at one of our small local swapmeets-a guy had a NOS balancer, he had 273-318 written on the box. I knew it was the same-I scarfed it up for 10.00.
