looking for measurements for trunk floor braces (Edit, willing to pay $50}

[Black Goast]

I have a 73 challenger and I'm looking for info on the location of the trunk braces, the ones that hold the fuel tank in place. Also looking for the hole size in the trunk floor for the filler neck.
Edit. willing to e-transfer $50 for the info. The body guy is asking me everyday, so he can move on with the project.

Thanks in advance
