Rear spring shackle bolts

Post by Rumbler »

What's the correct shackle bolt for early 1928, hex head or square head? I couldn't find this in the RG&JS.

FYI - Early 1928 = through April 1928 - RGJS page E-107

Initially the bolt had a 1-1/8" hex head (see figure 4 upper
image). Beginning in April 1928 through May 1929 the head
was 1-1/8" square with rounded corners (see center image). The
head was then changed back to hex beginning in April 1929.

Thank you, Neil. Informative response as always. My April28 truck has hex head bolts, while I also have a July28 frame with rear springs that has square head bolts, hence my confusion. And then I couldn't find the RGJS reference. But now I know that each frame is correct for their respective month!
