Roll cage

[JIMP]

Hello,

was wondering if you could help me with the following: I need a decent roll cage for a 1303 (let;s say a 6-point minimum), but don;t know much about them. It must be something real, (not for show only), don't know if it can be from aluminium or definitely chrome moly. It must be bolt-on and the rear seats are not an issue. Is any manufacturer across the Europe that has something interesting?

Thank you
JIMP
