3820929 shock mount

[Timothy B.]

I have the outer strut/shock mounts off my 67 and found the 929 (drivers side)mount has been replaced by the #265 HD suspension mount. The other side is the correct 3820930 mount and I want to replace the drivers side to be correct so if anyone has a 3820929 mount that's in nice condition please contact me private as I want to get my car back together.Thanks, Tim

Tim,

I have a pair of used 3820929/3920930 shock mounts that I bought is a box of misc. Corvette suspension parts at Carlisle many years ago. Unfortunately I did not notice that the 2 mounts were hack-sawed off at the end with the cotter pin hole so they are junk. One is forged "3820929" & "2DC" and the other is forged "3820930", "GP6" and a large "2".

I also have a NOS set of 3829265/3829266 mounts. One of them is forged "3829265-66", "1", and "E". The other one is forged "3829265-66", "3", and "E".

There is currently an NOS "3820930 RH" mount on Ebay (not mine) if you don't mind coughing up $100 plus shipping.

The next time I crawl under my 1966 I will check the exact forging numbers on the shock mounts.

The likely reason that you have the HD mount is that the HD mount replaced the original 3820929 mount for SERVICE in February, 1978. So, after that time if a shock mount shaft had been replaced, GM would have supplied the HD mount.

Many of these mounts were damaged by corrosion and/or during removal. Inspect yours for corrosion damage which often results in serious pitting of the shafts. Pitting seriously weakens the shafts and makes them prone to breakage.

Joe,

If you have one HD service replacement and one original, is there any reason this would cause a problem from a functional standpoint? Isn't the angle different on the HD shock mount, to allow more clearance for the HD shock absorbers?

The configuration of the 2 mounts is slightly different as you describe. However, using a HD mount on one side and a standard mount on the other will cause no functional problems, at all.

Joe,

You are correct. Corrosion is probably the reason why the 3820929/3920930 shock mounts (as shown in the photos below) were hack sawed off.

Thanks everyone, if I can't locate a nice used part I will install the HD mount and wait until Carlisle to pick one up. It's not a big deal to change out later.
