Good morning LWS,
Just a word of advice, check to see if your car was built with the brackets to accept the hardtop. If it wasn't, I don't believe you can add them easily, thus, the new hardtop cannot be installed. I've a similar issue with mine. I'd hate to see you buy a hardtop and find you're not able to use it.
Good luck and have a great weekend. Go F1 !! Go Hamilton !!
Cheers !
