GT-Garage, that is quite an open question for a recommendation.
It might help it you tell us why you want a cage i.e. just for looks with an unmodified interior or are you looking for a weld-in cage with a stripped out interior for maximum stiffness/safety or something inbetween?
This should narrow your choices down.
got your mail, we dont have postcodes in the south of ireland .
guess ive to save my pennies, i have a do-luck mid strut brace, any pics of a cage installed , see if i can work around it , as i really wanna keep this brace .
