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
Check out Gerst Suspensions, very good kit.

Short of a complete coilnover conversion which costs a lot(stay away from the cheap ones like AJE, they're cheap for a reason and that equals failures)

There are only 3 coil over conversions I'd trust at all.

Gerst Suspensions aka GTS
Reilly Motorsports aka RMS
Hemidenny aka HDK

My suggestion is to call each of them, all are good guys and have years of quality products speaking for themselves. But be prepared to shell out between 2500-5000 for one of their kits. But when you add up the costs of upgrading the factory torsion bars, other suspension components and quality shocks etc, it's not much more depending on brand and you still have the room issues or lack there of .
