what dia t bars should I buy? & what shocks should I get?

i'm a penny pincher did mine cheap spent all the money on balljoints and bushes :)

and its perfectly adequate

KYB gas adjust and the bars out of a big block v8 A body
with the correct ride hight

mine came standard with a perfectly adequate sway bar and is an Australian car

60s B body width at the back
disk brake A body width at the front
8 inches shorter than a dart
so my gians my differ from yours if you did the same

but all i really did was make it work more like the day it came out of the factory.
i.e old worn out 318 bars replaced with old worn out 383 bars
probably landed me back at day 1 in a car with a motor that weighs about 3/4 of a 318

its a nice enough ride
