i had an idea for sealing up mine, a piece of plexiglass on a hinge that seals up against a rubber gasket. maybe i'll draw a picture if thats not clear enough..
someone on here did some ducting, and had pictures, but I dont remember who. I remember that they cut out the metal between the brake mounting holes on the strut tower to fit a round flexible duct in there.
I like it, but i also agree with the others like, where does it all fit in with the g35,350z,skyline mess... i like them too, they look good. but it seems like they're getting all too similar.
are you sure? i found this picture after a quick google search of 1970 laurel

haha.
I thought I had the same problem.
It turns out nissan used the same part for left and right, one is just flipped over. do a little search and you can confirm this to be true, if you dont believe me.
I'm trying not to sound like a jerk, but right snips will leave a nice edge if you use the correct technique. MOST sheetmetal workers NEVER carry straight snips [they're pretty useless], only rights and lefts. Make sure you're pushing the snips to the very front of the cut each time you snip, otherwise the cut ends up looking like a saw blade.
