69 BB oil cap

[Brad S.]

Is the rivet on the bottom side of the oil cap supposed to be round or square? Had car judged at chapter meet and received deduct for "square rivet. I think the cap is original but not totaly sure. thanks for any help

The pictures look just like my original 1970 SB cap. I don't know why a 1969 BB would be different, but WTFDIK?

My original early 68 has the same square rivet however, during spinning/peening, it looks sort of round but definitely started out square.

I do not think that the cap is supposed to be removed for judging. Same as gas caps, battery caps, etc.

They were both the same part number----GM #3851735. Every original of these that I've seen, including an example I purchased in 1970 had the "square" rivet configuration on the inside.

I agree with you Joe. I was less strident in my original post in an effort to appear not to be too critical of whoever judged Brad's car. I have been in situations at chapter meets where I was judging outside my comfort zone. One sometimes has to do what one has to do.

If you mean the retainers under the rocker arm cover fasteners? -- they are plain (unfinished) steel.

Terry , yes the triangular retainers under the v/c bolts. On chrome covers they were unplated steel? Were the bolts the same finish? Thanks again for the help

Yes I believe the triangular retainers were all unfinished (plain) steel. Rocker arm cover bolts were silver colored plate. I believe zinc, but I am sure some will say cad. Now let's see what others have to say.

There are several self appointed experts that do not think the rules apply to them.
