Welcome to the site

!
I am not familiar with the differences in the factory crossmembers, since I make my own for my application. Be patient and I am sure someone will give you an answer, the guys on here know these trucks well. I just wanted to give you my greetings!

Cotter, what year truck are you putting it in?
'64 and earlier will require modifications.
'65 and '66 are very easy if you use the 460 truck mounts '73 - '79.
Also for '65/'66, you will need to remove the secondary crossmember, the one that fastens to the ends of the radius arms.
Grind off the rivet heads and pop them through.
Remove the upper mounting bolts, and it comes right out.
The existing transmission crossmember will work just fine as well.
But that is only for '65 and '66 - '64 and earlier is much different.
