F15a steering knuckles

[Jacques Reed]

Now I am confused (More so than normal!)

While putting away the knuckles I photographed for the earlier post I noticed the Part number C01Q 3358 cast into one of the knuckles as per the photo attached. None of the other two knuckles had any numbers cast into them.

Very different to the F15A parts list numbers I quoted.

It definitely came off a 4-7/8" steering end as used on the F15A. Still, as is often the case, it does not mean it is the correct one.

I don't have a parts list for the larger trucks with 6" steering ends and would have thought those knuckles would not be the same size but could it be?

Anyone able to shed some light on this one?
