So I got a ford fiesta mk4 a 1.3, and I have the car for a project for motorsport.
But am having trouble finding a mk4 roll cage and am curious if I have to use a different type of car roll cage if I do which type? Or is it same roll cage as a Mk3 or do I need get a custom one built?

 

Would have thought safety devices would do one and expect you could adapt an earlier or later one.
