G'day Vlad,
Yes, the lining does push up a bit, but I didn't want to go too far as it may leave a permanent dent in it. If that doesn't worry you, push it up hard against the roof.:D
The metal strap is just a larger version of what you get with an after market stereo to support the rear of the radio. Something soft enough to bend to shape, but not too soft that the weight of the console straightens it out.
As I said before, you will spend more time on the design & template than you will making it.
It's worth it though, apart from the $$$ saved, the satisfaction of doing it yourself is great. I'm still getting compliments when people see it.:clap2:
