Ford Repair: 69 Mustang Fastback Fram, mustang fastback, subframes

Question
I am rebuilding a 1969 mustang fastback and I was wondering if it is possible to replace the original subframes and torque boxes with a solid one piece rolling frame from another car?
I think that this would make it more stable with less flex and alot easier to rebuild.
If the answer is yes, do you know what frames would be the best fit?

Thanx

you can use a frame from a mustang two.there is alot of modify to be done.i would stick with the orignal frame.if the orignal frame is in good shape,its very strong.unless your building a all out racing machine,what you have is fine.hope this helps.
