The Aussy one appears to be the same as FV228288. see attached.
Spare book shows castings for chassis no. 20 000 and above, where does that put the Aussy chassis at 13 000 + 14000?
Can't quite believe the differences in one casting for a short production run of vehicles. I assume these would have been ripped off, when the armoured bodies where fitted, as the inherent design flaw would have been quite obvious by that time. Which would also mean that you should have bucket loads of these castings lying around over there.
Maybe one of the designers had shares in a casting plant?
Obviously the longer legs on the "Y" are able to absorb the manifold movement.
That is the first uncraked short "Y" I have seen.

Not sure if your gasket fitting hammer is quite large enough.
Rich.
