I looked up the part and the only one shown for 86 aspy is the 44800-MG9-013 for the whole assembly and 44806-MG9-003 for the gear only.

I may have misled you, I looked up 86 model at first then went back when I realized you have an 84. You are correct, there are 2 different listings. No explanation of why. Knowing Honda parts system there is no difference other than price.
