Swing Arm Spacer Tube

I need to replace the spacer tube in the swing arm on my 07 Speed Triple. It is marked as obsolete on both World of Triumph and Fowlers . Part no T2067340. Any ideas gratefully received.

 

I'm sure a machine shop could make you one, if you have the old one as reference, or the dimentions.

 

I've measured it up and it's just standard 30mm tube with 1.5mm wall. I've ordered some stainless and will get it cut to length squared off.
