I'm being told the crankshaft damper bolt that AMK is currently offering with the triangle on the bolt head is not correct. Attached is a photo of the crankshaft damper bolt from my father's 1970 Dodge Coronet R/T (440). It's a little tough to make it out, since the bolt head still retains some paint and it was exposed to elements for the first 10-years of it's like. Does anyone re-manufacturer the LE bolt.
