I don't think I would be up for "blasting" but maybe ladders and getting another detail item replaced that is MIA, and that is the Flammable placards and holders. I just reduced the ladder project by 1/6 as it looks like 12757 is correct
The placard holder appears to be sheet metal applied to the running boards on each side and ends, so 24 each required. Here is an image of a placard that looks similar to what was used that I could reproduce for application as well. If someone has an actual sample placard that I could copy then cranking out X number to offer as fund raisers is in my wheel house.
