Did anyone make/still make a roll cage for a 405? I'm thinking someone must have made a fair few as there were plenty of 405 rally and touring cars. Or would they have all been custom ones?

I am in need of one as well.

There is a company in Italy (OMP I think) who make cages but I got no reponse from the local agent so I don't know if they make a cage for a 405.

Even if someone had some drawings then that would be a help.

Otherwise I suspect I will have to design from scratch.

Loads of companies around that specialise in it as i'm sure you're aware. Just that the 405 isn't all that popular for cages i'm sure.

Could easily use their existing designs to fabricate/fit one for you, shouldn't think it'd be cheap though like some of the off the shelf bolt-in ones.
