well I got another Type R emblem but it turns out it's the front one not the back one, so the prongs are much thicker - Tried to force it in and I ended up breaking one of the plastic pieces that go on the trunk. Are those replaceable? I'm gonna clean up the glue and stick the emblem on with glue but at some point I'm going to fix that...

 

3M adhesive works fine. you really dont needt eh prongs, they aid is assisting when putting the emblem on so it is even. just using as adhesive is sufficient.
