Ladder bars..??..

I'm considering ideas for my next project for the car.. of course the theme of my car is old school so a ladder bar rear suspension seems synonymous with old school.. at least to me.. I have a parts list started but I'm not exactly sure what I need and what I don't... Right now I have the 0 0 2 in the 0 0 3 leaf springs and was wondering if I should trade one of those out to have them match? Again using the ladder bars as my primary traction instead of the leaf springs?..
any help on getting this accomplished would sure be appreciated and this is what I have Summit dream cart LOL...

originally I never thought about the floating housing mounts but once I seen them it seemed to totally make sense...
