Rear Springs

[Havoc 2]

I have a 99 cobra vert that has a solid axle conversion.
The driver side sits an inch and a half lower than the passenger side.
I need to replace the springs but do not want to make it lower, the x pipe already drags.
What springs need to go in there?

Replaced rear springs with new ones made for the 1995 thru 1998 mustang gt
everything is fine now.
