Question about motor mounts????

[sam's 72]

I am in the process of changeing out my engine. I have the motor mount towers that has the hole in the center, and the bolt goes through and bolts up to the motor mount on the engine. I really don't like these type. What I was wondering. Can I put another set of towers on my 72, that take the clam shell type mount? Where the bolt goes through ( side ways ) through the mount on the engine? These are the ones say off of an 81 through 87 truck. I hope I wrote this to where you guys understand what I am wanting to do. The oringal mounts on these trucks are hard to deal with, that is why I would like to change over to the clam style motor mounts if possible.
