69 barracuda dash to firewall bolts

I definitely would not remove the windshield, or take it to a shop to do this.
I've played around with a couple different screw/clip styles, combinations. I have a pretty good assortment.
No pictures of mine and my dash is at currently my painter's shop. I'll probably have my dash in and out a couple times before I install the windshield.
My 2¢ fwiw

*Edit* I guess I should add that I'm talking about my 69 Barracuda Fastback.
