Will 70 Coronet springs work on 69 RR?

Just started taking out my rear suspension on my RR. It has the standard 5/4 leaf suspension. I also have the rear springs from a 70 coronet R/T that has the 7/6 leaf spring count. Will the R/T leaf springs bolt in place and if so how will the ride differ?

Yes they will fit. 6 on the drivers side 7 on the passenger side. Depends if the R/T ones are in decent shape, it could sit higher, it'll handle better.
