Roush need new springs to raise my car

need new springs to raise my car because it’s too low I bought it this way, it’s like driving a log wagon. the two short front frame rails are damaged i think from a jack stand from the previous owner. i want to get subframe connectors The question is, do I get new springs first or do i need to fix the frame rails first? it's an 89 mustang i want Eibach Pro-Kit and i have no idea what springs are on there now.

thanks in advance
