As above.
I bought the item above, but it doesn't fit my Monza jacket! I am trying to find out whether I can return it or not, but it might cost more to do so than i'd lose selling them on. I think the fitment issues are because mine is a part of a 2 piece suit. I've tried two different sizes and both are miles off.
Alpinestars Tech Spoiler, size L, in black. This is too small for my jacket
It should fit most Alpinestars jackets (size 50 - 58 ), but clearly not mine. £20ono
Feel free to make me an offer. I'm in London, so I can possibly deliver in some parts of London, but i'll post it wherever for a reasonable price
