Who like a Mystery?

That number looks more like the part number for the bracket. It also looks like a typical GM part number, aside from the last digits.

Thanks. Rob, cheers

The chassis number on my C15A is stamped on the left chassis rail just behind the front spring shackel.

Hi Tim, I just took some photos of a C60S chassis,
1 chassis no.
2 front rear shackle
3 back rear shackle
From these pictures you can see that the spare holes you showed in your second picture are for helper spring stops.

Thanks Robert, those pictures are really helpful.
I will have to head out to my truck again for another look but when my friend and I looked the other day we couldn't work out where the rear hangers would go as no holes seemed to marry up with the bracket having the two rivet points on the side and two from underneath. But with your photos I can have a better look. Thanks and cheers. Tim

Tim post a fiew photos of the chassis from further back. Is it possible the springs are in the right place and the chassis has been shortened in the middle.
