Re: Marsden nuts
A 1936 did not Originally use marsden nuts. From 1935-41, a 3/8-24 hex nut was used and then from 42 up a 3/8-24 thin marsden but was used. The original 35-41 links with longer threads are hard to find. The service replacements and reproductions have shorter threads with the intentions of using the thin marsden nut.

Re: Marsden nuts
1935fordtn is absolutely correct. You will have to look at your shock links and match the length of threads with the type of nut you use. Most shock links that are usable are service replacements or reproductions and therefore will take the thin Marsden nut. The original shock links not only used a 3/8-24 hex but a lock washer as well.

Re: Marsden nuts
Actually, and with all due respect, Marsden nuts began to show up on shock links in early 1939 - as I recall it was February / March of that year.
This was the time when the stud length was shortened.

Re: Marsden nuts
The idea is that when you tighten them they deform from the threads pulling down on the inside and the mounting surface pushing up on the outside making the slotted part go inwards and lock.

Re: Marsden nuts
In modern parlance you might look at what is called a Grade "C" all metal lock nut.....it is "thinner" than a nylon type lock nut, slightly thinner than a standard finished nut & strong, and "might" work for what you are doing IF you cannot find what you are looking for. You will have to scuff and paint them as they "generally" come in clear zinc coated. Just a thought if "originality" is not as important

Re: Marsden nuts
This coincides with what i'd been told, that the shaft on the shock link was shortened to provide a margin of safety for the larger tires of the Mercury, introduced for the 1939 model year. This was also one of those confounded parts whose configuration was changed without changing the part number.
