1973 duster door tag sticker

any one out there know where i can find my cars front and rear and total weights? also month , day and year of build.? its a 1973 duster 340. I want to get a new door sticker/tag. I called the guys that reproduce them and he said he needs that info to reproduce a tag, I have the vin # and build sheet, but on the original tag that is on the original door---that was replaced, I can not read any thing on the tag. any where else I can find the info I need? thanks much
