Subframe the easy(?) way

I made it to the Pypes car show this weekend. It seemed a bit bigger than the other years I have gone.  There was a beautiful white Mach 1 fastback with a 460 and flat black side pipes peeking out that was just incredible.  It is one of those where you see it and just think, "if I could just have that, then my car itch is completely scratched for good."  no camera :-(

I was looking at the engine mounts in all the cars.  I am again not liking the little 1.25 tubing that I am trying to sneak through that tiny space to hold my engine.  Everything at the show had very stout mounts.  I started thinking about some alternatives.  I was wondering how the mustang subframe dodged the rack so I took a look.  Then started thinking I should just modify and use that...

The engine mount has a pass through for the rack.

Yeah, I will just have that, and amortize the mustang expense over some more harvested parts: 

Briefly contemplated leaving the control arms on and just using the mustang suspension.

The good:

track width is right

better brakes

no bump steer

ackerman

The bad:

shock towers are off by about 4 inches per side

Height is wrong

Wheels not in the right spot for forward/aft

Here is a view with the subframe up under the car.  I think I will nibble a bit off the spring perch to let it pass inside the rails.   Maybe I can make some brackets to mate with the rails and then hold the frame.
