I am a first time user and this is my first post. My 35 Standard Coupe has shocks for each wheel. The front two are the round Model A type. but each of the rear is a horizontal casting of two tubes (one above the other). The top tube has a large circular cover with a hex bolt type face that is designed to remove the cover. The bottom tube does not have a removable cover on the front, but a like cover on the bottom front. This cover is also designed to be removed, however mine is on so tight that without undue force I cannot remove the bottom one on either the left rear or right rear shock. The right rear shock top tube is full of fluid. The left rear shock top tube is empty. I have not been able to find anything written on this type of shock. The right shock top tube is full of fluid (I presume 10 weight mineral oil, however this is only a guess as I do not think it would be brake fluid) On the back of the shocks at the top of the to tube is a square nut plug that is removable and I have been able to remove and reinstall this threaded plug on both shocks. The left shock has had the shock arm nut removed and the the end of the spline shaft beat on to prevent removal of the shaft. The right shock has a nut on the spline shaft and the nut can be removed. When I manually lift the left rear of the car up and down repeatedly by the top of the fender at the wheel well, there seems to be no shock function. Doing the same on the right rear fender, there is almost no movement. It is like the left shock has no fluid and the right shock too much fluid so the left shock is essentially doing nothing and the right shock is locked up. What little written information I have been able to find tells me that apparently 1935 was the first year for this two tube rear shock design and not all 35 vehicles came with this style shock. Others came with the Model A type round shocks, but the shocks are interchangeable. I think the way it is supposed to work is fluid transfers from one tube to another through an orifice and the direction of fluid movements depends on whether the shock arm is moving up or down thus dampening the axle/wheel movement. I do not think the shock tubes are supposed to both be filled as it appears to be on the right shock but it should have more fluid that is in the left shock. I have no idea what the fluid level should be, type of fluid or how to load fluid into the shock. I suspect that the removable plugs at the top rear of the shocks is where fluid is added. Please help me to understand how these shocks are supposed to work and direction to any written material and diagrams on these shocks. Also, I had the car restored by what was represented as a "professional restoration shop," however given all the things I have found wrong on the car, I don't think it was too "professional." One of the things is the small arm to which the end of the rear shock arm attaches. With the car sitting on the ground the short arm was sitting on the back of the axle tub to spring mounting bracket and showed some wear. This was true for both rear shock arms. I removed the shocks from the frame and positioned the small arm so that it is vertical to and below the shock arm but also vertical and above the axle to spring mounting bracket. This means with the car on the ground, moving car body up and down does not cause this small arm to touch the axle to spring mounting bracket. A picture would be worth most of these words, but I am presently more than 350 miles from the car so cannot take a picture. Anyway, I sure will appreciate any help that any of you can provide.
