I have searched and haven't found the answer yet I am looking for on this question

I have a 1984 5.0 LX 'vert and the front end sits a good .5" to 1" higher than the rear...My goal is to have the opposite rake to the front

I have been looking online at spring choices and the very few that say for 'verts only are out of stock, but also don't show much of a drop. I am also looking at the BBK progressives for hardtops.

Will the hardtop springs negatively affect anything in the rest of the car? Also, to get that rake to the front will I have to modify the front springs likely?
