1973 duster door tag sticker

There is no way for him to know what the MDH code is. That's why I wouldn't guess at it. The weights can be found from other cars...that's not an issue. When I had mine done at ECS, I told the guy over the phone what my sticker said. As long as the VIN number is correct, AND he can't prove the sticker had a different month then the SPD on the fender tag, I think he is OK to say June.(since that matches the tag) ECS will know for sure.
