Car Photographer - I hope you get the rear arch mountings sorted.
And just remember the grille isn't "wonky", it is "hand crafted".
Good luck, Paul.
PS
Old Jock - Please start a separate build thread for your car, as it makes it much easier for others to follow your progress.
Especially, as you appear to be doing a full "nut & bolt" restoration.
As the old saying goes...
"Two build threads are better than one."
