Jordan , thanks for the measurements, Yes I did make blanking board out of mesh , but it was a ruogh square cut, basiclly to cover the hole, but want a wooden one made just for show, i'm in a sticky wicket again , I have a mk1 drivers seat but no gunners seat so I i'm just going to make a Mk2 gunners seat , fairly easy , just all angle iron& bits, but both seat backs are a mk1 , this is so in my travels if i come across a mk1 seat i'll install it. Lets just say my Mk1/Mk2 is a mixed bag even putting sum Mk3 parts in it purhaps. Cheers
