69 c-10 vin plate location

[1969stepside]

so i have a question. the vin plate on my truck was removed by the body shop to fix some rust that was around it. the vin plate has not been changed my question is what is the measurments for the location for the two plates that go in the door jam. i am asking you all this because the owner of the body shop that had my truck has passed away so now i am left answering questions and figuring out what was done. i want to state that this vin is the vin that goes with this truck so there is no shady stuff going on with it. i just need to put it back where it belongs. the truck was made in canada if that makes any diffrence. there is a gvw plate and a vin plate. any help would be welcomed
