Midyear big block rear end

[Jeremy H.]

What is the correct color and headmarks for the bolts on a big block rear end side yoke cap? The four bolts that hold the caps to secure the inner u-joints.

Thanks

The bolts were 3/8-16 X 1-1/2" and were zinc plated. They were untrimmed (i.e. "indented) hex head, GM-280M material grade (SAE grade 5--3 line) and one headmarking was "RBW". I'm sure there were others.

Thanks Joe, that is what I am using. I got them from Paragon, I have other supplies that send me black phosphate bolts. It doesn't say what finish or headmarkings in the JM.

Do the Paragon bolts have the "RBW" headmarking? I didn't think that they reproduced any "RBW" fasteners, but they may now.

They are RBW bolts
