I had a similar problem on my bug. The hood flew up and busted the hinges and i couldnt repair it to work right again with new hinges. so i put hood pins.
here are some pics
(please exuse the nasty trunk..these pics are 3 years old)
i made some mounting brackets for the pins out of raw steel. then drilled holes into the trunk liner lip.
here are the Sparco sliding hood pins i used
heres how the hood comes off now.
Hope this helps...sorry i didnt see the post sooner
