Suspension Options?

Hello, I am new to the forum and I just recently became the proud owner of a 65 Barracuda with a 273 V8 4bl. I am wondering what my options are for suspension conversions for the vehicle? the torsion bar set up leaves a little to be desired. I am looking to free up space under the vehicle to eventually run better exhaust/engine upgrade. Is there another A-body that I can transfer parts from, or am I stuck at dropping big bucks for custom components/Lots of fabrication time? Any information would be greatly appreciated.

P.S. If there has been a discussion on this and I missed it please direct me where to go - Thanks
