I have been looking around for one spare valve cover bolt that fits a Chrysler 440 for my 68 New Yorker. From what I have read, the same bolt was used for valve covers for the 340, 383, 413, and 440, (possibly the 318). Apparently someone had used a non-factory style bolt but since I have been working to restore the car to its original parts, I wanted all the bolts to be the original style without having to buy a set for $35. Most everything on the car is original and I want to keep it in the preservation category. My local salvage yards and parts guys have NOTHING of the kind. I was really surprised after millions of Chrysler engines were built using the 1/2 head with 5/16 threaded bolt. Anyone have a spare? I'll create a thread with pictures on the work soon. Thank you!
