Leaf recommendations?

Finally able to buy my replacement parts for suspension rebuild. Obviously its been a crazy year and money is tight.
Among other parts, Im upgrading to 1.03 bars. Im wondering if its a good idea to go ahead and do the leafs now too. It might price me out of my budget, but that what credit cards are for...lol.
Im not sure exactly how to identify my current leafs, but there are 5 leafs. The bottom being that very thin one. So like 4.5. Measure 2.5" wide and 35" from center to rear eye. On a 69 Dart...originally a /6. No part #s I can see.
Looking for replacement recomendations please.
Any other info u need, let me know.
Thanks
