Mustang 2 kits, coil spring?

[J48chevy]

I see on some of these kits they tell you the spring must be cut as they all come standard 13.5" length springs. I know this may sound silly to the experienced guys here, but remember I am new to this. When I tried to install my springs, as I posted on another post, I cannot bolt up the shocks. They just do not line up. When I take the springs out, mount up shock, it appears that I will have to compress the springs a good 4 inches to get them installed. Does this sound right or will I need to shorten the springs some? I know the mustang 2 kit automatically lowers the truck about 4 inches and do not want to go much lower. Just frustrating getting these springs in.

Thanks.
