The radiator stays are 11" and have a small bend. The crank guide is 8" and has a sharply bent end. I do not recognize a part that size.Could it be one of the radiator stays.?
It is just a 1/4" fine thread.There is a screw or bolt that threads into that hole you see in the bottom of the crank guide. Check you parts bin for one that might fit. I am in Florida and my car is in Canada so I cannot tell you the thread size for that hole. I also used a star lock washer. Good luck hunting.
