QUAD SDQ63 (Stand and Delivery) stands

Hello,

I want to put my ESL63s on stands. SDQ63 stands are no longer available and rarely found used.

I found an iron shop that can make me a pair. I have the width and depth but I need the inner height. Per a photo that I have it looks like the vertical bars are approximately 2½" [63.5mm] by 2" [50.8mm] and all the other parts seem to be made of 2" [50.8mm] steel.

Would any owner be kind enough as to send me the correct specifications?

Thanks much in advance,

Horacio
