h&r springs on a fox vs sn95?

i'm thinking of buying a set of used h&r springs did research and h&r application says...

h&r app stated: "1997, Super Sport, V6,V8, R1.75, F1.6, #51652-77"

guy said even though for 97, it work fine on his 94.

can i make this work on mine? Have any of you done this before with springs?
if so would it sit lower or higher, give bad ride, any feedback would be great..

1989 h&r app stated: "1989, Super Sport, V8, R1.5 , F1.0, #51650-77"
 
i took the h&r coils off my dads 95 cobra after he fractured his neck in a accident, schwab just swapped my stocks coils off my 88 gt with his and they worked perfect. id think 87 to 98 would be all pretty much the same. i dont have facts on that, just a guess.
