I don't know about everyone wanting to install those 1st Gen braces. Those braces are steel and won't give any. Isn't it overkill? My thinking is the braces are there to make sure the chin spoiler doesn't flex at speed. You don't need something that rigid to do that. So if you ever do bottom out the nose a little bit I can see those 1st Gen braces ripping through the spoiler instead of giving some. Obviously anything serious it won't mater. I made mine for my '72 out of one of those thin metal hollow broom handle. Found the length, flattened both ends and angle them. Drilled a hole in each end, painted them black and voila.
