69 barracuda dash to firewall bolts

I don't mean to rock the boat here. It has been several years since I had my dash out and my memory isn't what it once was. Having said that... I don't recall the 5 OEM bolts having the pointed nose shown in previous posts here. They were black coated machine screws with kept washers. Combination of 'U' nut bottom and sheet metal of dash the end of the bolt just barely reached beyond the threaded neck of the 'U' nut. I couldn't imagine it ever reaching the glass but I knocked off half a thread of the length at the bench grinder anyway. 16 years later I know it was all a waste of time. I'll never remove the dash again.
