Speedo Blowout picture

Does anyone have a blowout picture of how the speedo is put together? Mine came in 10 pieces and am trying to figure out how to put it together. This if for a camaro 86 but they are the same up to 89. I went to a 145mph unit but the guy sending it to me dropped it and the needle spring broke. Since there was nothing holding it together all the pieces fell apart and now I have a jigsaw puzzle. Not too many parts but it is missing screws also. A diagram would help me put it together.

Thanks,
Mike
