Camaro Clip Measurement. Help!

[Kartch1]

Hello everyone! I have been lurking on the board for a long time and it's been a wealth of information. I have finally started to dig into by '56 project. I got a little ahead of myself on the teardown and removed front and back suspension. The problem is now I am getting ready to put on the Camaro front clip but I don't know where to place it because I can't measure wheelbase because rear axle is gone.

Does anybody have a measurement from front of body mount bracket to center of upper shock hole or something like that I can go off of? If there's another measurement you suggest instead that's great. I also want the center the wheel in the opening as well.

Thanks so much in advance if anybody can help me. I will post some pics of my build if anybody is interested.
