Dash mount

On a 66 Dart the are no clips. There are tabs coming off the firewall top that the screws tighten into. I guess I will try drilling out the screw holes for short bolts to come up thru, then use nuts in the top side of the dash. With the windshield out and no gasket in place I will just grind the bolt down to even with the nut. I'll have to look and see if I can tack weld the bolts in place to make installing the dash easier as I will be working by myself. My dash already has gauges in place so will have some weight to it. Thanks for the reminder.
