What leaf springs to buy

I just installed the 3" lift springs from Springking on a 64 Barracuda. They actually lift three inches. Quite stiff, six leaves....
Haven't driven it as the car is still apart but they seem well made. They were shipped quickly. I am pleased with the Ebay deal..

I tried a pair of the 2" lift 5 leaf springs from ESPO and they settled down to just a a hair over stock height in about a year or so. My experience with ESPO has been fantastic otherwise. Put the stock Espo five leafs on my convertible and another on a 64 Barracuda. I also used a pair of five leafs from JC Whitney that were shipped from JR Spring that were inexpensive and are workiing well.
