Who has good suspension parts?

[El Sol Infinito]

I am definitely needing new rear leafs, shocks and the whole bushing/shackle/u-bolt/pad shebang. I have a shop that'll do the install that I like, and they say they have "t-bird" leaf springs, but they can't specify whether these are HD or convertible-specific, so I'm hesitant to go with their components (even though their component price is GREAT) Does anybody have a preferred source for these parts? I've heard that Eaton spring is great, but they are SO expensive ($400/pr plus shipping). I've also heard of an outfit called Springs n Things that have had mixed but mostly good reviews, but their prices are GREAT ($170/pr). So I don't know.
Thanks,
Bob

I just installed a set i got off Ebay $151.00 plus shipping $52.00, Conv. springs. Car looks much better sitting up a couple inches. You have to put in your bushings and change the center bolt. I did it myself but i have air tools and jacks and it's a pretty heay job. Thunderbird headquaters has the complete kit springs, Bushings, Etc.for about $440.00. I tyhink it may include new u bolts.
