Ok, so, I have an 87 RX and a shop replaced my distributor and they apparently had "a Subaru 1800 distributor out back" and put that in. Its been running...more or less now for about two years.

 

I went to look into its misfire/stuttering problem further when i noticed the part number was 22100-AA440.

Everything i find in reference to that number is a GL-10. I would like to know if its the right one, a new one says the part number would be one of these:

22100-AA450X, 72649003781

 

Is the random site i pulled those numbers from full of crap? are these distributors different at all?

the full list of numbers is:

22100AA440 D4P86-03 A A703

 

do i have the right distributor?

All optical distributors are interchangeable. If it runs then it's the right one.
