Genuine tonneau support bar dimensions - help please

I'm in the process of making a replacement tonneau support bar for my HQ ute (it was missing when I bought the ute) and I'm having trouble getting it to 'look right', as well as stopping water pooling on the tonneau.

Can someone with an original support bar pleas measure the height of the support bar (centre of the bar to the tray floor)? I assume HQ to WB would be all the same.
Thanks

A mate of mine has a Spindrift Blue Aug 84 4 speed V8 WB Kingswood ute with just over 100k on it which he bought new. Being a Kingswood it came standard with tonneau and bow. We measured from the top of the high rib in the centre of the tray floor to the top of the bow and it measured exactly, and I mean exactly, 500mm. Hope this helps.
