Along these same lines . . . to an extent anyway.

How difficult was it to get the cowl 'eyebrow' piece that goes under the windshield in place?

Mine's a bitch and more than likely I'll install it then paint it.
No use painting it and then scratching heck out of everything else trying to get it in.

And . . . if I'm missing a trick here I'd be happy to hear how you did it.
