What subframe best fits 58 Apache?

I am needing some help deciding which subframe to use. Ive heard of both being used but dont know which is the better. I have access to both a 73 camaro and 78 nova. Which is better for my 58? Also if anyone could help with some details on the best to go about installing it would be greatly appreciated. Reference points to be specific.

thanks

Do not use the Nova to much work to rework where the bumper bolts on.Look at both clips you will understand.ASK ME HOW I KNOW.Jimmie King

 

I used a 79 Z-28 camaro clip on my 58, Easy!
I worked on a friends 57 with a Nova clip. it was much more difficult.
