I was recently looking up the Tokico HTS102 short stroke kit for the ae86 when I came across this:

There is a link for an 84 GTS and a 86 GTS
On the 84 link this comes up:

And on the 86 link this comes up:

My question is, is there a difference between the 2 HTS102 kits? Will one not work in the other year model?
What if I own an 83, 85, or 87 model? Sorry if the question seems a bit n00by, I was originally planning on just buying a GReddy Type S coil over kit but after some research I've found that a Tokico HTS and TRD/Swift spring was the best route.
Your help would really be appreciated!
