Polycarb Windows, Securing fronts Options

[dommorton]

Hi,

I have done a search but can't find the answer so forgive me if this has been covered countless times in the past.

I've just started fitting a Polycarb Window kit from ACW Motorsport Plastics (may I say the quality of their product is fantastic). I had the rear quarters fitted in no time using base spec fixed rubbers. However It's the Doors that are causing me some head scratching. I've been trying to figure the best way to secure the windows in the up position.

Though about just putting bolts through the runners however this proved near impossible to measure and fit properly in such tight confines.

I would like to avoid drilling into the windows if possible. Can anyone point me in the right direction please?
