Today I installed the Rear Cab Mounting Shackles on my 1953 3600.
Only tricky part is that the cab has to be raised above the frame so that the mount holes line up with frame. I used 2x6’s on a floor Jack to raise rear of cab cab.
Not a bad job - good Pilates crawling under truck of course...
Below is a stock pic of what these look like.
