Race R tail section?

Hey guys I'm looking into the sd-r tail section from here: http://www.perfect-fairings.com/en/prod ... ce-tail_22

Ill be converting from standard SD so what else will I need for the conversion? It looks like the under tray portion is molded into that section but I can't tell...

Thanks!

Dunno but the race mask that I brought was so bad that I never used it. It is still in the box it arrived in...

This looks like the worst quality bodywork I have ever seen. Be careful. Its just not expensive enough and it looks like the mould was made from old potatoes and cast in lasagne pasta sheets.
