first Gen Front Suspension Dimensions
 

I want to build my own subframe to hold C4 components for my 67 RS, I'm looking for some basic measurements and Geometry to use a starting point. Can anyone help me?

If you are using a C4 suspension you will want to use the C4 mounting points. They are available here...

Download the demo and print out the geometry sheet.
Design your cradle around the C4 components AND steering rack.

Thanks for the info, I've looked over that program before, but I don't remember seeing the C4 stuff in the demo. I also have the original cradle that the parts came from, but the engine setback seems too far to fit in front of my firewall. I'll take a look agian at the program. thanks, I've already done the C4 IRS in the rear, check out the pics in the new users section...
