Actually the holes for the dashboard screws line up really well. If you use pins in those holes to keep it lined up it all lines up pretty well. Where the lower plenum and firewall are pinched together it has to be filed down because the new cowl doesnt overlap far enough it seems. It's got a curve down at the front, so those 2 pieces have to be filed back a little bit. On the sides where it overlaps, I may have to cut and draw it in a little. With as hot as it's been out here lately, I will likely wait till october to sandblast all this, and get it in primer.
