how is the ecs sticker material different from original?
also, the ecs sticker is stamped 79 for inspector. not every car would have had that inspector so it become kinda cookie cutterish. is it best the buy a blank sticker and pick a random number for the inspector?
Yes I think you have discovered what allot of others have - that it appears to be a one size fits all product.
Those (reproductions as well as the ones through most of the mass marketers) are vinyl stickers were the originals were paper with an adhesive backing. Also ECS makes only one version of the stickers rather than all of them, used at other years and plants
ECS reproduction shows the stamping (way it was filled out) that seems to match 69-73 or so Dearborn inspectors not the other plant and years
Inspectors did not always used numbers to identify themselves. Just like paint inspectors (for examples) at San Jose some periods of time it was numbers, other times initials. For paint inspectors during other periods it was even a first or last name. Haven't documented names on inspection stickers as of yet
As far as the rest of the information it again goes back to plant and time period. The CHARGE could be the hydrostatic reading in (if I remember correctly) 100's) or a simple OK. Dates would be hand written in black ink or pencil or stamp with or without a year. Just depends
