Hey Crew. I removed the broken shackle bracket from the left rear. Here are a couple of shots from the right side. The shackle looks just like the ones on the front. Is that the correct one??

Hi Tim,
They were the same front and rear on my truck. (the shackles themselves, NOT the brackets)
Tim

I have wondered what the front shackles looked like. My truck has no front shackles or brackets. Are the brackets and shackles the same on the front and rear?

As Tim said above:

The rear shackles should hang straight down, like those on the M101 trailer. Check out my painted ones in my tailgate painting post (freshly painted on the green tarp-last picture....)

The shackles are the same, front and rear. They do not change throughout the truck's production according to the 1955, 1960, & 1973 editions on the parts manual.

Well Mike's post got me digging because I was certain my original response was correct. Guess it depends on your point of view: My 20P manual dated 1955 has the off-set shackle, as well as my Ahl Resto guide. However, my Army Motors #125 shows the prototypes with straight shackles front and rear (and they look goofy on the front, hanging at a 45 degree angle). Anyway, I'll second Mike's response but admit I prefer the straight shackles on the rear.

Gary,

Can you scan the page with the straight shackles from the AM #125 and post it here? I've never seen these before.

Sorry Bert-no scanner.....

I saw a set of straight shackles on e-bay motors. I'll see if I can find them and I'll post the picture on here Bert.

I don't have a clue what these are other than I saw them on e-bay motors listed for an M-37 and a few other models.

The Army Motor's article has three photos of pre-production pilot trucks with two showing the straight front shackles. There are 8 production truck photos of both pre-55 and post-55 trucks with the 90 degree lay flat type.

The 1954 ORD 9 and 1957 ORD 7 lists 4 each shackles ORD PN 7373735 CC # 1268540. The 1972 TM 9-2320-213-20P lists Shackle, FSN 4030-737-3735 (ORD # 7373735) 4 each.They are all the 90 degree lay flat on front type.

The three photos below were from the Army Motors 125 issue.

Not trying to hijack the thread, but Cuz's pictures bring up a question. The pre-production truck is equipped with combat wheels. I have heard that some of the early trucks had them, is this fact, and if so, up to what year would have had them?
Thanks,
Tim

Only that one pre-production truck had them. If you read the article and look at the other two pre-production trucks the one in the first photo was the only one to get them.

Thanks Wes,
Good info, and from a trusted source!
