1967 front shocks ?

[Keith G.]

Should the big washer on top of the front shock be what color? And what kind of nut or nuts?

The upper retainer (washer) has an oiled, phosphate finish. The color varies a bit but is usually a light to medium gray. The nut was a heavy duty nut of 3/8-24 thread size and 21/64" thickness. It was phosphate finished. As a HD nut, I believe this nut was 5/8" or 11/16" across-the-flats as opposed to the normal 9/16" across-the-flats for 3/8" thread size nuts.

here's the washer, as Joe describes -- it may still be available from GM. 2nd pic shows original front shock (early '65) with what I believe is correct top nut.

The 3790342 is no longer available from GM, but it was available until just a few years ago.

What is the across-the-flats dimension on the nut?

I thought they were all 9/16 "wrench size", Joe. I'm curious to see if others think they were not.

It may be 9/16" wrench size but GM lists it as a heavy duty nut. Usually, a HD nut has a larger wrench size but sometimes it's only a matter of increased thickness. I don't have full specs for this nut that includes wrench size.

Joe, Chuck -- the nut in my pic is 0.555" across the flats and 0.325" high (via caliper measure).

OK, apparently this HD nut was HD only with respect to its thickness and standard with respect to across-the-flats dimension. The thickness you report is just what I have in the specs for it that I do have.
