Nut
A nut used in the cylinder barrel and head assembly, cataloged as 70-4103 (formerly E4103).
70-4103 is a nut listed in the cylinder barrel and head section of the parts book, with the earlier catalog form E4103. It's a small hardware item, not a headline part, but it's the kind of thing that goes missing off the counter or the shelf when you're rebuilding a top end.

Our records place it in catalogs spanning 1963 to 1964, tied to the cylinder barrel and head assembly. The catalog entry itself doesn't spell out thread size, material, or exactly where in the fastener stack it sits, so we can't give you more than that without guessing.
If you're working through a top end rebuild and need to confirm this is the right nut for your engine, give us a call and we'll go through the fitment with you before you order.
