I'm pretty sure you won't get a definite answer to your question.
I would buy the 2" drop springs and trim them if you decide you want it to set a little lower.
Anyone else have input on this?

Small block springs and big block springs have different spring rates for the difference in weight. It wont ride right. It would be like putting a ton of **** in the bed to lower the rear. Yeah its lower but it rides horrible.
