Top bow extension measurements?

[blitzdough]

Sorry for the odd placement, I didn't see where I should ask this one.

Would someone be so kind as to post the measurements for the tube extension pieces that the top bows (for the canvas cover) fit into?

Thanks!

Chuck, the set I have for my M3 has 3 different sizes:

14 3/16"

18 3/8"

22 1/8"

Hope that helps. It was a set I got from Outsider. I'm not real sure how they set in the track

Thanks Don!
