A friend has just brought a VY 1-Tonner and asked me to have a look at the deck mounting to see if I knew why it has extensions on top of the Holden chassis. It looks like the extensions could be removed to make the deck lower ? Any help on this one ? Thanks Mark.

Yes, you need photos. Not clear what is meant.

They don’t need to be raised. The “bearers” on the tray that run front to back sit straight on the rails. They are normally about a 3” C section. The tray boards then run across the C sections with a perimeter section that holds it all together and also hold the hinges. The tank parts that sit above the rail level tuck in under the boards. Sometimes they will have mounting brackets though to lift the tray up a bit. You would need some kind or riser bracket for the front mounts though. On the original 1-tonners they had bolt on supports up the front that the very front of the tray C sections sat on with a bolt holding them down, and you just used a pair of big U bolts on each side that held the C sections down to the rails.

If you move the filler neck can it be lower? I remember some of the older alloy trays purpose built for HQ-WB had a scallop in the perimeter rail and a gap in the tie rail for filler neck clearance like you have done.
