Lock Washer; GM # 103328

Re: Lock Washer; GM # 103328

The original St Louis installed lock washers I have are all thicker and have squared edges, some are knurled most are smooth. They were unique and I always stashed them away when I could. Many new lock washers have more rounded edges. It may be as simple as finding a heavier speck lock washer for the current suppliers.

Rich,

Your comment about the 103328 lock washer being thicker is consistent with what the one person told me yesterday. I've yet to find a modern lock washer of that diameter with a thickness of 0.184".

Gary,

You may not believe this, but Ronnie G. has some NOS ones and the finish if my memory serves me correct is black oxide.

Thanks for the specs, John.

That minimum thickness is interesting, but not so relevant if they all were in the 0.184" range...

Guys, a huge mea culpa. I screwed up. Big-time.

I just looked at my notes and found that the measured thickness of an original bumper lock washer is 0.141", not the 0.184" I mentioned several times in this thread. Therefore, it appears that the AMK washer is accurate in size.

That's what I get for trying to remember my notes without having them in front of me.
