Does anyone know the body mount dimensions for a 1974 Camaro?

No idea what you are referring to. Unibody car. What measurements are you looking for and why? Are you talking about the sub frame in the front?

I am referring of the front sub frame body mount dimensions. I need the diameters of the holes and the mounting pads. Also, the distance from the front to the middle and the rear mounts. I have researched this and found that 74 Camaro dimensions are different from 1973 and 1975. I asked these questions because the mounting pads on the sub frame were severely rotted and I welded in new pads. I need to know the whole dimensions for the new body mounts. and the distance between them. Any information you could provide will be very much appreciated. Thank you!
