Houdaille lever shock identification

[Mark L]

First I want to apologize for asking a question that's been asked multiple times. Within the past hour I found a post here that had photographs attached in response to a similar question, but now I can't find the thread after searching for various combinations of words.


Anyway, I found two Houdaille lever arm shock absorbers in the trunk of a 1951 Studebaker along with a set of Ford overload leaf springs. The Studebaker had tubular shocks on all four corners, so they were not from that car. Studebaker did use Houdaille rotary shocks on their cars prior to 1951, but the ones I've seen used a different style of lever arm. I'd like to sell the shocks since I have no need for them. The springs have already been sold.



I ** gently ** restrained the shocks in a vise and verified they are not seized. I did not tighten the jaws down on the body. I just used it to keep the shock from rotating when I pushed/pulled on the lever arms.


The bolt holes in the lugs are round and tight on the bolts. Other than surface rust, I don't see any damage or bent links. Neither shock is leaking (but I really don't know how much fluid is still inside). They were difficult to rotate by hand, so I suspect they are nearly full of fluid.



These are the details about the shocks:


Dimensions:

Shock body diameter: 3 inches
Shock height: 4.25 inches from the mounting face to the tip of the shaft
Shock mounting lugs: 3.938 inches center to center
Lever arm: 7 inches center to center
Side link: 12.375 inches center to center

Identification marks:

Shock “teeth” are stamped P 1X 7 2 2 0 (both shocks)
Shock bodies stamped P1647 H and P 16 47
Lever Arms: F-1215 on one side and 1 U 2 on the other


The tip of each shaft appears to have an adjustment mechanism.



Also, see the attached photographs.


Questions:


Were these used on a Ford company product (Ford, Lincoln, Mercury)?
What years were these used?


Thank you for your assistance.

Google Houdaille.

There was a good post last week showing shocks ford used and the different arms. Your shocks look like ones ford used but others may have used them as well. The links do not look like ford ones and may have adapted the shocks for some other make.

I’m running Houdaille rears on my rear end, and MGB rears on the front of mine.

Prior to posting my message here, I did search the internet for several hours. That's how I was able to identify them as made by Houdaille, but none of the information I found definitively identified them as a particular assembly number or year of manufacture. My impression from the Applehydraulics website is it looks like they use some of the same photographs for different assembly numbers. I independently found the bulletin that glennpm attached to post #6, which has great photographs, but none of the numbers on those pages match the numbers stamped on mine. It does help identify what mine are not, and narrows them down to fewer possible assembly numbers.
