Help with leaf spring selection,

Hello all and Happy New Year,

Since my car has changed focus slightly from more drag oriented to street and handling oriented I will be removing my Cal Trac split leaf mono springs, bars, and shocks. (2000km on this set up, will be selling). What would be a good leaf spring choice?

The suspension now consists of boxed LCA's, reinforced k frame, adjustable strut rods, 4 Bilstein shocks, PST 1.03 torsion bars, flaming river manual steering box, delrin LCA bushings, new ball joints, moog offset upper bushings, Hellwig tubular sway bar. I am looking for rear springs to compliment the front end.

I live in Canada so currently shipping and exchange are quite costly, I have good friend who is the parts manager at local Dodge dealership and gives great pricing on Mopar stuff. I have heard horror stories of xhd springs, perhaps they have improved? What about Mopar circle track springs.

Any comments welcome, I'm not opposed to shipping from US but I've already spent a fortune on this thing this year so if I can save a bit it will help.
