they just look like rivits but there not... i had the same problem.. just get some good needle nose or some needle visegrips... and just make sure you grab them good.. and just turn them likee a skrew and they will come off like a screw.. and if i was you i would put regular screws after that... so if it goes out u can just replace it easy.. yea honda didint want people replacing them so they did that lil tricky thing.. they wanted you to replace the whole throttle
