Roll cage diameter/circumference?

[gledy2]

Hi, can anyone help please? My car isnt with me and i was wondering what the roll cage diamater or circumference is? I checked here http://www.nobleforums.com/showthread.php?t=3340 and the yanks say 1 3/4". I measured it before but forgot to note it down and i thought it was 11cm circumference which is 1 3/8" diameter which is different but i cant remember correctly!

It is the cage in the middle ot the cabin for mounting a rear view mirror on as it has a screen for a rear camera and my attempts at making a mount from a helmet cam failed when it vibrated too much and fell off! So looking to get a clamp on the roll bar for it.

Cheers,

Allan

Just measured mine - over the thin foam covering - at 45.6 mm diameter. So the steel tube is probably 1 3/4 inch diameter (44.5 mm).
