not familiar with any production bolt head like that ?

Re: Are these right for 1967

There is one thing for sure!!!! St. Louis did NOT stop the line to make sure a bolt had a certain head mark on it. That's a grade 8 bolt and would work on anything it would fit.
And you say, are you sure of that? Well, they didn't stop the line for hoods, hub caps, jacks etc. etc. did they?
I can assure that bolt is not typical of any mid-year and does not appear anywhere on either of my 67 Corvettes.
But that statement don't mean much if you read the first paragraph!

Keith,

The photos below are for a 67 base engine, fairly late, June 29, 1967.

Although the alternator and brace has been off a number of times, I believe the bolts are original to the car.

Adjusting bolt:



Lower brace:



SBC painted

Alternator lower pivot:



Note the painted lower bracket bolt to the manifold. Here it is cleaned off:



I don't think this one has ever been removed, maybe loosened a little.

Remember this is a 67 base engine, it might be different with an L-79 or big block. Fairly late, 6/26/67 engine.

Notice the triange between the hash marks.

Re: Are these right for 1967

Keith,

the triangle is referred to as a Delta headmarking and was not used on midyear cars.

Gerard,

all yours are typical assembly line headmarkings. The grade 5 Alt adjuster bolt is a nice one. Most midyear top alt adjusting bolts were grade 2 with a few slipping through as grade 5.
