Stud (4,5 in. O.A.)
A 4.5 in. overall-length stud used to secure exhaust fittings to the engine, cataloged 1964-1969.
This is a stud, listed in the parts book at 4.5 in. overall length, and it turns up in the engine fittings and exhaust system section. Studs like this thread into the cylinder or head casting and give the exhaust system something solid to clamp down onto with a nut, so the pipe stays put against engine vibration and heat cycling.

The catalog carries this one under 70-3695, with 70-3685 and the older E3695 form as the same part under different numbering. It shows up across a run of catalog entries spanning 1964 through 1969, so it was used more than once in that stretch, but we don't have the specific model tied to each of those appearances.
If you're replacing one, check the length and thread engagement against what's coming out of your engine before you order, since studs in this area can look similar but aren't all interchangeable across different fittings.
