I've seen it mentioned that if you put 2wd rears in front they'll give you about 2" lift, but I never heard about the spring rate. What is the difference in ride and actual usability? Do they have a similar spring rate, softer or harder? I have a low mile set off an 87 2wd I've been parting out and they look to be in excellent shape, so they would do the trick for now. I don't wanna move my mounts so newer toy springs or longer springs are out of the question, but if I do a sas on my 86 then I plan on doing waggys or something like that. Lemme know if you have any info on this, Nate
