LSL Steering Damper Size

Gday,

I want to see if I can use an LSL dampner mounting kit to mount a WP damper (that I already have) on my 05 SD can someone pls tell me what is the Diameter or circumference of the LSL so I can see if the WP will fit into the bracket.

Thanks in advance
Cameron

To the best I could measure it is 7/8"
