Need help with front sub frame swap

I've seen the pictures of your great white brick project, it is what got me to think that I could also do that to my cuda. Great work!
I just don't know if the 68 Valiant frame will work for my 65 cuda. I will take some measurements of mine and go have a look at the 68. If anyone knows for sure one way or the other if this frame will work for me please let me know. I want to go have a look at the car today.
