T-Rex 600 skid ends.

[RotaryOne]

Has anyone any spare skid ends for the Align 600 skids please?. I specifically mention Align skids because there are alternatives but the metal on the tube is thinner and the hole larger than on the standard Align skids.

I know that skid ends are available with the u/c kit but not, it appears, on their own.

Thanks in advance to anyone who can help.
