Interesting idea on the spacers... wondered if that was how they did it, there must be enough wiggle room to take up the change in hood angle at the header panel and latching mechanism.
Now.... hoping some eagle-eyed folk might be able to offer thoughts on the door decals.
In the second race scheme (as bought) each of the front doors had the following decals along the bottom edge, as first picture below~
Schiefer-Hurst-Lakewood-Fram-Valvoline. Then a Cragar decal (which fell off) on the bottom of the fender.
In the 1971 Lions photos, second pic below, I can make out the following~
Unknown-Valvoline-Holley-Hurst-Schiefer. The Cragar decal is under the Z/28 emblem at the front of the fender, and another decal I can't make out at the bottom edge of the fender. There is also an M&H decal just rear of the door by the quarter louver.
Does anyone recognise the unknown decal front edge of door bottom (reminds me of a Coca-Cola logo to me, with the twist underneath.....) or the unknown decal at the bottom of the fender?
