1963 to 1967 Rear Valence Outer Bolt 121893

[Richard M.]

In need of the correct 121893 bolt for the rear valence outer ends, I recalled I may have had some bolts removed from our.....(actually my wife's) 1963 Coupe when I did work on it about 8 years ago. Well, I found them....

But I'm confused. I had them in a bag marked "original". I checked both the 1963 and 1967 AIMs, and they show a separate washer used under the head of the bolt, Item #7. Part# 121893.

Both 1967(left 2 pics), and 1963(right 2 pics) AIMs list the same bolt part#, but with different "separate" part# washers under the head, and the same part# nut.

Do I have original 121893 bolts here? Was there a change to this bolt within the 5 year C2 production?

They are headmarked ELH. They have a integral washer, a protruded self aligning tip, and what appears to be a self threading or locking end. Over the years I have heard conflicting information regarding this bolt. i.e., with washer, without washer.

Rich
here are the bolts, washers and nuts from my Jan 64 coupe and I am 99% certain these are original.
the washer is a separate part. The bolt is about 3/4" long.
I bought a second set of these for my 65 from Rich P.

Know you also discussed the washer part numbers and if individual; Here are the P.Washer specs. Other info I have (GM books) call the 63 SMALL while the later 67 as LARGE. Both of these are in Gr 8.929

Chester, Sorry I'm a bit confused.....

Are you asking? "...Does any vendor sell these bolts?" ?

or are you stating? "Any vendor sells these bolts." ?
