anybody....?

Personally i cant see an issue. It would be good for someone who has rebuilt these things to pipe up tho. Potentially the box channel style would be easier too.

Cheers!

I had a look the other day and wondered why you wanted to change it. Was there a particular thing that you didn't like? I like the flash cad drawings but really couldnt see the gain.

If you were to mount the body on rubber mounts then that might be a little different, and make it 4 inches wider and coil springs and ......

Looks generally good to me.

I'm assuming that the assembly process will be to install and weld in the tube, followed by the bracket, followed by the chassis mount so that you can full weld.

The one critical flaw that I can see which applies to you as a modifier, but does not apply to the manufacturer, is that the flap that the manufacturer has used on the top of the chassis rail.... despite them doing this, you are not allowed to weld the top of bottom plates. You wont get it approved by the engineers if you do this. Just end the plate on the corner of the side and top of the chassis and weld it in there. It will still be as strong, but will also be complient.

Thanks Guys,

Thats interesting Simon. Thanks for that. Does that apply even if I fit a standard one again.

Pete, assuming the QLD modification laws are the same as NSWs etc, then only the manufacturer can weld the top and bottom chassis plates, so even if you fit a standard one again, you still cant weld the top and bottom plates. The engineering reason behind it is that the forces that go through the chassis are carried by these members, and the sides are only there to maintain the seperation of the top and bottom plates. Thats why you can weld the sides only. When you put welds down on it, then you are adding stress raisers to the plates and for a number of reasons it will make it prone to cracking. The place where you see this most is on trailer draw bars, where people weld across the top of them where they first meet the trailer body - a no no, they should just be welded down the sides only otherwise they eventually crack through.

Man! Thats a devil of a thing. Almost as bad as lifting the trailer onto the roofrack. Thats exactly the thing!
