unorthodox pulley

Have someone installed the unorthodox pulley from a 91 to 98 240sx ka24de on a sr20 before?Is possible to install it and is it going to work fine?
I see that the pulley has the same 6dots for timing but I am not sure if works for sr.
Thanks guys!

If you look at the sight I’m pritty sure there difrent part #'s for the sr and ka. But I have never installed it befor so I’m not a 100%. But if your willing to sell it Ill buy it off you.

I’ll probably get a ka this week or so, if I don’t get the ka I’ll sell it np!
Thanks for the info.
