What clutch did you get? I remember when I got my spec clutch (over $500 :smash
I was f'ing pissed because they did not include the alignment tool, ended up buying a universal tool for like $20.00, came back installed the clutch and when I went to throw away the box it came in guess who I found wrapped up in a whole bunch of brown paper??....that's right, that sneaky little mofo... LOL moral of the story, check the box very well!!!
to your question, I do not know if the 5.0 tool would work on a modular, but they are both 10 spline, so it would not hurt to try. Test fit/ align the clutch to the flywheel (without the pressure plate, doh!!) and see if the disc is centered in the flywheel, if it is you are good to go!
