64 Dart Suspension Upgrades

Im looking at upgrading my suspension as much as possible in the next few months. My goal is to improve handling and comfort, as it’s a bit rough as-is with my worn suspension parts.

I found a kit that classic industries sells to convert my rear-end to coil overs from the stock leaf springs. I want to keep the ride height the same but I think that will bot only improve handling but give me a better ride all around over leaf springs. Does anyone have opinions about that?

As well, I see that a company called AJE makes a tubular k-member for the 62-66 A-bodies. I don’t know much about that brand, and am afraid it might not be worth the money.

I’d like to do coilovers all the way around, if possible, but I’m not sure what mods I’ll need to make to let that happen.

Edit: I’m considering the Hellwig sway bars as well. There’s a lot of body roll as it stands right now and it makes cornering tough. Everything is too soft

I figure if I do change over to tubular I-member, perhaps tubular control arms would be in order to improve strength over the stamped steel ones I have now.

As always, any thoughts, advice, etc. Are welcome. Thanks!
