early a body v8 tortion bar question

hey guys. i have a 65 valiant that i will be rebuilding the front end on. it is getting the big bold disc swap and the c-body tie rod ends. it will also be getting the lower control arms boxed. it will be a driver but i want it to handle better then stock. car is factory /6 car and will now be a 360/904. it has the factory bars in the car still and i would like to upgrade.

1. are all a-body bars the same?

2. what would you guys recommend for bars? i want it to be better then stock but not be jarring. the wife will be driving this car alot.

cost is a big factor here. i have seen used bars for pretty fair prices but dont know what will suite my needs.
