pattern for 65 barracuda trunk divider

I have to make one too, but looks like it could be measured using the hindge as a guide for width and figure distance to where the latch would be... and just round the corners??? or maybe it was more involved. have buddy with 65 cuda parts car but the wooden thing had rotten beyond recognition!! LOL
saw a 65 cuda going dowen the road other day but the cummins dodge couldn't catch him! who said it takes a mopar to catch one!!???? LOL
